"The analysis presented today at the Rencontres de Moriond quantum chromodynamics (QCD) conference used nine times more data from the Large Hadron Collider than the 2015 analysis. The data set was first analysed in the same way as before and the parameters of the previously reported Pc(4450)+ and Pc(4380)+ structures were consistent with the original results. "
The Standard Model
home.cern/science/physics/sta...
"Our best understanding of how these particles and three of the forces are related to each other is encapsulated in the Standard Model of particle physics. Developed in the early 1970s, it has successfully explained almost all experimental results and precisely predicted a wide variety of phenomena. Over time and through many experiments, the Standard Model has become established as a well-tested physics theory."
The Physics Still Hiding in the Higgs Boson

"That’s one reason she and many of her colleagues want to build a bigger, better machine. The first phase of the proposed supercollider has been nicknamed the “Higgs factory,” because the machine would collide electrons and positrons with energies precisely tuned to maximize their chance of yielding Higgs bosons, whose subsequent decays could be measured in detail. In phase two, the giant machine would slam together protons, resulting in messier but much more energetic collisions."

*Starts to explain the standard model from the beginning*
Ah shit, here we go again
Hate these people to talk about standard model as a fact.
@@Majlo2L8 They referred to it as a "widely accepted scientific theory," which is an accurate description 1
Also, even if there isn't any proof that the standard model is complete it explain a lot of the fact that we have sperimentaly discover and vice versa; so as long as we don't find any better teory the standard model is optimal to use; it's like classic physic and relativity.
The standard model is just a map of the particle energy measurements. The only reason it isn't "fact" is because nothing in science is fact, only a compilation of evidence. Theories are always being tested and refined for precision and accuracy.
The theory is not complete. It is self-consistent and makes successful predictions, but does not fully explain some things that it should.
I feel you.. its painful to watch her struggle this much.. go get hank.. or someone actually trying to explain stuff
I wanted more... like 23 minutes more of this... it felt like a warm-up...
that's seeker for you
23 minutes? dude I wish I could have a fuckin IV drip of this shit directly into my brain 24/7. Break our brains, Seeker. Break our brains so hard.
You want more?
Then head over to PBS Space Time.
It'll make this seem like a grade school primer.
Agree with everyone here, PBS Space Time is the best when it comes to astrophysics, QFT, the standard model, and Cosmology, Matt (host and writer) said in the patron video that the entire purpose of the show, is to share the bleeding edge of science with anyone who wants to learn it.

The first half of the video about the Standard Model basically summarised what I learned about particle physics last year
Cool story bro
For those who already know about the Standard Model, 4:04 is where the video starts.
If you are really in a hurry, then no, there is nothing new at all. Just another composite particle.
Thanks for the TL:DR! 😀
AHAHAHHA lov u
i agree, there's no "shift" in the standard model I can tell
I just made exactly the same point.
This is one of the best introductions I've ever seen. My son (10yo) can grasp it. Thank you!
I am interested in other simple breakdowns of "color charge" and "spin dynamics".
Joseph Fuller so glad you liked it!!! That was the goal :)
Joseph Fuller
Fundamental particles have intrinsic properties that affect the way they behave in collisions with other particles! An example would be the electric charge of a particle. Electric charge can be either positive or negative, but quarks have a special intrinsic property that behaves very similarly to electric charge except that there are 3 states, so it doesn’t make sense to call them positive and negative.
Additionally, observations of protons and neutrons show that the three quarks that make up that particle must have all three states of charge present. The quarks switch between the states in a complicated fashion, but all three states must be present for the proton or neutron to exist.
The scientists who discovered these used an analogy of how mixing light of multiple colors creates white light. The white light represents stable hadron, while the colors which make that light represent the three different states of charge that quarks can take. Over time, the three different states became known as color charge, and a system for naming the different charges with a color has been adopted in much the same way that we refer to states of electric charge as positive or negative - for convenience in calculation and communication.
This color charge is important for determining how these particles behave in collisions, because color charge must be conserved. For example, it can be deduced whether a particular outcome is possible by whether or not the conservation laws will be violated if that product were to be created.
Spin Dynamics:
Another fascinating intrinsic property of elementary particles is called spin. These objects are not actually spinning, they simply have an intrinsic property about them which behaves in many ways analogously to how a spinning object would behave when trying to apply a force to it, and the engineers at the time used this word and it stuck. Motion is only caused by a net force, and spinning objects resist changes to motion in a very different way than a stationary object does due to their angular momentum. It takes a good bit of research and practice to really grasp, but there are some great videos if you type “bicycle wheel angular momentum demonstration” and you can see what I mean. Basically, when studying electrons, engineers use electric and magnetic fields to probe their properties. The electric and magnetic fields apply forces onto the electrons which cause it to have motion. The motion of the electrons in response to these forces is very similar to the response of a spinning object being pushed on by a force, and so while they were trying to figure out what the intrinsic property truly was, they were using this spin analogy to communicate and calculate, and it has stuck. Basically what you should know about spin dynamics is that electrons have an intrinsic property about themselves which causes them to behave slightly differently in the presence of electromagnetic fields than would be expected just given their electric charge. Ex, given their charge, we expect one result, but experiments show very tiny (yet significant) deviations in results due to this intrinsic property called spin.
Hope these explanations help! Basically, our experiments show that certain values are conserved before and after a collision. Conservation laws are one of the most useful tools in an engineers belt and we use them all the time to solve problems. Color charge and spin are the result of trying to find conservation laws that match experimental evidence of the subatomic particles.
@@MarenHunsberger Thank you for the reply to my comment. ^^ I often enjoy your videos more than other hosts on CZcams as you have a very calming voice and usually a very clear style of presentation. There are only two other hosts that I think are better; the narrator of "Top 5s" and Jack Finch of "Top 5 Scary Videos" as they are simply the best!
@@cooper7655 Wow, thank you for the info. It is a bit dense, but I will give it a closer read on the 'morrow.
@@cooper7655 A question for you that allways trubble me , given the fact that you know this things :
Electrons are fundamental particles . The Weak Force is also fundamental . Now , the electron doesnt get to c because of the Weak Force via Higgs bosson or , The Weak Force is born from the fact that the electron has spin and charge .
I guess my question is : Both are fundamental ( spin, charge ) / ( the weak force ) ....So , they are equally fundamental?? As we know , the electron doesnt exist ( not as a particle anyway ) .....So , that makes The Weak Force more true to the word Fundamental ??

Wow i need start school from zero again
Well good luck ! Even after you realise it's weider
In my experience, most people do.
Seems like very few paid attention the first time through.
Or just watch porn and let others figure it out.
Perhaps it is time to consider that the proton is always a pentaquark (five quarks) and not the traditional three quarks. It's quite possible that as accelerators become more powerful, that the increased energy separates the remaining two quarks (the quark and anti-quark pair cannot be detected until separated). Three quarks were detected for many years with lower energy collisions, but now we're likely to see a lot more pentaquarks in the future.
Great video, very well organized, and elegantly narrated.
So clearly explained. This is what a well-organised video should look like.
Just watching this makes me feel intelligent.

I think einstein and robert penrose are thinking that gravity doesn't have a particle because its not a force but a consequence of the geometry of space-time expanding

The title is clickbait. It implies there is a new subatomic particle and that the standard model is changing. Neither of these things are true. The topic is interesting, why do you need to frame it around a lie? Why is this a thing?
Pc(4312)
its called marketing. and... this whole thing is the Most wasted billions of dollars ever. Complete pseudoscience funneling.
Both of these things are true, this pentaquark is new and it is subatomic. It's also exploring unknown behaviors of standard model thus shifting our understanding of it.
But what you probably read from it is that there is new *elementary* particle, which there is not and that standard model is turned on it's head, which its not.
It’s a CZcams science reporting channel, they don’t really understand what’s going on they just like to report it.
Click Bait says hello
You guys rock, thanks for all the work u put on this!
Talk more about pentaquark, in particular:
1. How do they know it was made of five (5) quarks?
2. In what way *could* it shift the standard model? I know it was recently discovered, so that needs to be researched, but give an example of how a previous particle shifted the standard model, perhaps one of the exotic hadrons. Maybe explain how things shifted once they looked into 4 quark hadrons. Just to whet our curiosity about future research.
3. What was the lifetime of the pentaquark, compared to other exotic hadrons? Does that give some clue as to what new discoveries are to be found?
4. Under what conditions did the the pentaquark form? I don't know what are the relevant parameters, but I am guessing: temperature, particle energy, magnetic field density and how it compares to the formation of other particles. That can give us an idea of how difficult and rare it is to produce such an exotic hadron.
BTW, bravo on the overview of the standard model as we know it now.

Nice video, very informative.
Maren, this was amazing, as always )))
6 minutes about the standard model,
1 minute about the main topic of the video..
color charge? please explain
It’s an attribute of quarks like electric charge which can be either red, green or blue, and accordingly antiparticles are anti-red, anti-green or anti-blue (but it has nothing to do with actual visual colours, the naming is all just convention that sort of gives us an analogous way of understanding it). The net colour of something made of quarks must be neutral, which is accomplished by either having e.g. a red quark and an anti-red quark in the case of mesons, or by having one of each colour, red, green and blue like in the case of baryons. Gluons also have colour charge, but for them it is never neutral, they carry net colour.
Aviv Shlevin color charge is held by quarks and glouns.
It is the thing that keeps quarks together and is essentially the strong force.
It is like the electromagnetic charge, but with color charge.
It is important to note that there isn’t any actual colors flying around, it is just a useful name to describe the phenomena, like how we call a strange quark a strange quark.

**insert funny joke cause im early**
Thank you for making this video.... It at least gives me a baseline to work from.
I, for one, would LOVE to see more on charge and "color charge." How does it differ from normal charge? Is it "partial charge"? Are units of "charge" divisible? If positive and negative charge are "indivisible", how exactly does three-way charge work? Are the "color charges" just fractions of the same charge protons and electrons have? How does math explain 2 up + 1 down vs 2 down + 1 up quark having +1 vs 0 charge (2x + y = 1, x + 2y = 0)? Since electrons are not made up of quarks, do some quarks even have a non-positive charge?
All questions I'd LOVE LOVE LOVE a detailed explanation on, because quark-charge is the most confusing part of subatomic particles to me.
