- The lifetime of the Higgs is so short that you can't in any conceivable way "see" it. How do physicists detect it then?

I can still understand the maths 🤯 so keep ‘em coming these episodes about particle physics.
I'm impressed by his skills writing mirrored
never underestimate a lefty.
I was looking for this comment
They used a software to reverse the image. He would write normally.
That’s probably his right hand and the image is flipped.
@@aggelosphyzx4065 no, look at his buttons on the shirt. Buttons are always on the right side of the shirt, holes always on the left. Maybe not 100% of the time, but he puts his mic on the same side every time. He's really just that talented
Respect to Mr. Cern for writing a flipped text just so that it would look proper from our direction.
This is SUCH a good explanation! Very very clear. Thank you!
LOL!!!!!!!! RIGHT !
Amazing, thank you. The best explanation of what higgs is and how you discovered it!
Fantastic! I'd like some more of these to spend time on quarantine haha
just fascinating! I thank you 🇪🇺
Brawo, super film! :) :)
Incredible, very nice explanation, thank you :)
Watching this in my underpants and not understanding a single word.
Amazing explanation
When he start explaining in Math, I stop watching and start reading the comments
This is really interesting and hoping to see more videos like this
Part 2!!! Nice
So well explained
Great explanation. It's funny how after being out of high school for 18yrs I actually understand E=mc²
Superb.thank you
This might have been the most expensive youtube video ever created..💰
I love Science ♥️
Let me at first show my gratitude to you , I'm an Iranian middle student who is interested in particle physics very much . May I ask that what did you mean by walking along the higgs ? did you mean to imagine walking along ?? or detector really moves ???
question !
consciousness is inside the DNA...........?
IT'S TRUE ??

Nice - please make more videos :-)
More to come!
I haven't looked at the comments yet. It may already have been asked, but in his model, they start with a Higgs Boson. If the higgs boson cannot be detected then the matter you are smashing together to replicate the moments after the singularity; wouldn't it just be electrons passing through the higgs field? I keep hearing and reading the Higgs Boson has been detected. But every time I read a journal or view videos discussing it, it turns out they haven't seen it, only mathematically can they determine the decay. This video is very well put together, i just don't understand how you start with a higgs boson either at rest or moving, but if it never materializes so WTF.
SO DIFFICULT ,THANKS A LOT
6:42 I wondered about this in the beginning and now he spells out it :-)
I love this :))
Beautiful
And people still think they’re alone at this quarantine
I understand the idea of adding momentum to calculate the energy but why do you square everything at 04:57 what does squaring do for you?
For momentum, mass and energy, the formula is only true when squared. Like the Pythagoras theorem: a^2 + b^2 = c^2, not a + b = c
I thought photons don’t have any mass, and that is the reason it travels at the speed of light?
Photons don't have mass, but pairs of photons can. Like a line has a length but zero width: | (ideally) but two lines can form something that has both length (height) and width: X Because "mass" of a system is not the same as the sum of all masses.
This is great stuff, but what I really can't understand is how Piotr manages to write flawlessly from right to left and in reverse.
The video is mirrored in post production?
@@folk. Either that or magic ;--)
Maybe Professors get lots of practice?
how do we know that a higgs boson will decay into two photons and also how do we know about the range of mass of higgs boson?
Here's another one why not station a side development and allow like AI to develop questions to understand the answers from the inside or see if your causing reactions in a bigger spread and not picking up on it
So here's another question like as you're saying you're using e equals MC square why wouldn't you use another box set up to see if it's the right mathematical complexity to even pick it up
But why are they so determined to find a theoretical particle so much so that they are able to spend billions of dollars and years and years and years of research just to try to find something that's a theory? I mean the amount of questions I have going to my head is a lot
like why this particular particle?
How was it thought up?
And what's the desired purpose that it's going to be used for?
I mean a product has to be made from it in order to justify the money spent.
The answer to life
@@gabrielleirizarry311 that's not convincing enough to get billionaires to donate their money towards and idea
There's a product apparently. "Anti matter" but I havent dived deep enough to understand. And im not the brightest crayon in the box.
@@gabrielleirizarry311 well what i know from personal experience is that money talks and in order to get investors to invest money you have to be very convincing and virtually guarantee that they will not only make their money back but a percentage on top for the time it took to return the investment and the largest investment the more convincing the sales pitch has to be and with billions of dollars being invested it has to have one amazing sales pitch that we don't know of because all in the name of Science and Discovery is absolute BS in the real world
Well if in the future we will have technologies that will make moving faster than light possible, this technology will probably come from researches like these. And that is I guess is enough to spend that much money to these.
Wish I could go here went to a show brown university had awesome 👏
Im not in this field , but what can we get out of this what types of technology could this create what could this information be used for ?
When we see an apple fall to the ground and we just wonder what makes that apple fall ...... we are not understanding that it is an oscillation of information in 2 phases.
We only assume 1 phase ... (the fall of the apple)
Gonzalo Garcia explain more of the “2 phases”
@@well7573 I'm not so sure but I believe he is referring to wave particle duality and the assumption of form?
I mean why not put a plant structure in there and see if you're going in the wrong direction see if your more destruction than you are productivity or try to see if you can control the understanding to participate growth
I don't think mc square ever changes. E square and pc square are always equal. Unless "ever" changes but, that's for beginners.
Here's another question like you said it only takes place I wasn't paying real close attention like 02 seconds why do you learn within that 02 seconds why wouldn't you learn against the 02 seconds
Once you expire the king of diamonds will be waiting for you you want a hellish future you've got one
😍😍😍😍
Me feeling like a scientist while watching this video then realising there are 50k others like me. 😅
The mass equation of Higgs bosons is very difficult to solve
Your furnace is set at 122 degrees ? Can you please turn it off ?
So, basically what saved the Momentum gaining problem of the Higgs Boson during its detection is selection of a proper frame of reference....
Keep in mind that invariant mass has been a core concept in experimental particle physics throughout its history. It is a "standard tool" used in the analysis of "boosted systems". For instance, see [1] for a nice summary of invariant mass in the context of W and Z vector boson production at the Tevatron's Dzero detector at FNAL.
[1] www.hep.man.ac.uk/dzero/teaching/z_boson2.html
how do we know which pair of photons add up among the many photons there are?
The ones going in the opposite direction ?
That's what the analysis is about. One needs to back-track them, match their spins etc., they should be in opposite directions and come from same vertex. Then only one can be sure.
@@luciddewseed3095 so they compare combinations of photons?
@@elflaco1557 Yups - that's the "Higgs to 2 photon decay channel" is about. You get a mass bump there signifying that this pair of photons is coming from a definitive particle aka the Higgs boson. Cheers
Magic
SWAG.....
One would look to ATLAS for finding out about how matter interactions become matter that builds particles that build quarks via phase wave interactions via new instrumentation that goes down to phase wave interactions that will read an electron phase wave output due to like all in this dimension an electron is a reaction system reacting to negative matter coming into this dimension since its conception at the big bang one would look at the Dirac sea equation, s for a starting point once you can read the electrons phase wave emittence cycle one is half way there to understanding how protons and neutrons emit to make said electron and communicating with it via phase wave emittence cycles to it and from said electron one is well aware one can generate electrons via s generator for power output but what else is this telling one DEDUCE YOUNG ONES DEDUCE
How did they figure out that the Higgs can only decay into 2 photons? Is that exclusive to the Higgs? Why?
The Standard Model theory allows H -> two photons as well as H -> 4 leptons.
English subtitle,please🙏😍🥰😍🤗
they're there, just switch them on if they didn't show up automatically

Why do we square everything? I get it, until it’s squared…. Why squared????
Don't the photons get a little bit blue and red shifted
Yes, the doppler effect can shift the photon's frequency/wavelength. As you probably know, the photon's energy is directly (inversely) proportional to its frequency (wavelength) [1]. The LHC experiments typically determine the energy of the incident photons from the amount of light produced by its scintillating calorimeters [2, 3].

And the heat is also a quantity of energy where is it
Heat is kinetic energy: www.vias.org/physics/bk2_03_02.html
Woo woo world
Why are you using something that's contained to spread like a wormhole what they say something that wasn't align correctly with your established equipment y e= mc² you know I'm a firm believer that equal is a structured rotation against development I believe in equal you're learning to decay not develop
Since lastten years u are still engaged in Higgs
Well who says physicist aren't cool
Commemorate the particles to be boson
Add the process don't measure add
Use the toy x-ray glasses see Proton
Old power
you got to be kidding me
How can we observe momentum and energy of photon
The LHC experiments typically determine the energy of the incident photons from the amount of light produced by scintillating calorimeters [1, 2, 3].

I am too dumb for this.
If Higgs give mass to the particles, then what gives mass to the Higgs itself?
Energy from the proton-proton collision! The Higgs field exists primarily in a non-zero energy state.
@@ricomajestic Well, I've no idea about physics or maths actually. I'm only an observer and curious person who wants to know the deeper realms... Is there any simple explaining sources about those topics that you can advice?
@@Rawk10 If you want to understand the Higgs field, Higgs boson and the experiment then check out the book by Sean Carroll
The Particle at the End of the Universe: How the Hunt for the Higgs Boson Leads Us to the Edge of a New World. He also has quite a few CZcams presentations regarding this and a bunch of other topics. He's a Physicist from Caltech that also knows how to explain things to the layman.
I think @Rawkon Ingenious, elaborating from ricomajestic's explanation, mass energy equivalence (via e=mc2) means that energy transferred from the collisions equate to a corresponding mass for the Higgs.
For the purpose of this video, the details don't matter. Sure they do.
We are Particle science researchers and we want to communicate to CERN concern people, can you provide email-id of the concern person
ugh, physics... I think my head just exploded. 🤓😵
U
Do we get to watch a mendela effect happen live?
Last time they turned on the machine we jumped dimensions when they turn it on this year it will have "world record levels" of power...pray for us.
Does your model incled the gravitaional pull that can only be attributed to the experiment on Earth?

50th comment
Thrive been using it in math as if it existsed for over a decade before confirming it. I'm always glad to learn things but this higgs is over hyped to justify the fact that lhc cost so much and this is the only particle they've been able to produce. There has been tech advancement in sensors but that's happening anyways the LHC simply accommodated a lab to test them.
Americans wouldn't build it because many said it's not going to be big enough to reap the rewards of say the lc in California that discovered like 12 particles.
Already got the over crowded particle field scientist wanting the next bigger facilty.
When you actually look at the % of confidence that they actually think theh are witnessing particles it's really low. They think it's actually like a 65% chance probably but theh are only 20% sure of that probability of the probability .lol
If course they speak of it as absolute fact. Its No such thing to begin with.
First rule of practicing qauntom is nothing for sure only probability.
Discovering new particles is not the metric by which we measure success in experimental high-energy physics (HEP). This topic is nuanced, so I defer to this CERN Courier article [1]. Your statement about "% of confidence" is ambiguous and wildly inaccurate. Have a look at [2] if you'd like to learn more about the rigor required of experimental HEP results in order to be considered a "discovery" and [3] for a glimpse of the review process that is carried out before results are even submitted to a scientific journal for peer review.

I know how to exist the life of boson
you are doing wrong
You can't solve dark matter this way
People are starving and you guys are spending millions of playing with particles
how you account for the expirment haping on Earth?
