Caterina Vernieri - "Delving into the Unknown The Higgs Boson at Future Colliders"

“Delving into the Unknown: The Higgs Boson at Future Colliders”
The Higgs boson was discovered in 2012 by the ATLAS and CMS experiments at the world’s most powerful particle collider, the Large Hadron Collider (LHC) in Geneva, Switzerland. This particle plays a unique role in fundamental physics. It gives all of the known elementary particles, including itself, their masses. While we now have a strong evidence that the Higgs field is indeed the unique source of mass for the known elementary particles, the next step is to search for new interactions that could also explain why the Higgs field has the properties required by the Standard Model of particle physics. We have no clear roadmap to this new theory but the Higgs boson plays a crucial role in this quest. The goal of a next-generation e+e- collider is to carry out precision measurements to per-cent level of the Higgs boson properties that are not accessible at the LHC. In this talk we present the challenges and possibilities for the next e+e- collider and recent progress. The exploitation of the complementarity between LHC and future colliders will be the key to understanding fundamentally the Higgs boson.

    Carl Sagan explains the many observations made with Discovery 1 and Discovery 2. The picture of the pale blue dot was taken by Discovery 1 . Today NASA managed to recuperate signals from Discovery 1 - 46 years after its launch - as it leaves the solar system and ventures further- far overreaching its goals. The James Webb telescope gives us startling pictures of galaxies that we could only imagine when Carl Sagan made this speech. But his message then is further proven correct by scientific evidence. We miss Carl Sagan today to give us a glimpse of this

    He was living in my hostel during his iit tenure, once we happen to work on something as an assignment in engg physics course I guess so I went to his room, was surprised to see he keeps footwear outside the room and asked me to do the same. Very neat and clean this guy likes to live (those who lived in iitd hostels would know what I am talking about😅) Great guy, loves to argue logically, he does not utter a single word which somehow won't connect with what's going on in the conversation.

    In a world where lies are the currency; telling the truth is a revolutionary act.

Thereafter you may host all sorts of plausible ideas as to motives

    As sunlight warms the surface of the Earth, heat radiates away from our planet as infrared radiation which passes freely past the atmospheric gases of nitrogen and oxygen. Indeed, if it weren’t for greenhouse gases such as carbon dioxide that do interact with and impede the escape of Earth’s radiant heat, the planet would be frozen solid. Thankfully, even though greenhouse gases comprise only 4/10ths of one percent of the atmosphere, they are powerful enough to maintain this ‘blanketing effect’ by constantly absorbing and releasing the infrared photons over and over, again and again. In doing so, they vibrate wildly, thus causing them to vigorously collide with other atmospheric molecules. This imparts the kinetic energy of motion throughout the atmosphere and registers as temperature. For more, search: ‘Enhanced Greenhouse Effect’; then ‘Amplified Greenhouse Effect’. For the big picture, search: Marcott reconstruction chart

    Some are meant to be read and not to be suddenly put under a spotlight. Ai, at every driveway, is already too far into the writer or theorist who retreats to isolation to work or study. That is the tripping point here. The phone is a stage in hand and the performer wasn't prepared for the part. A dark place behind the stage is the right place to point to the door or, some will bristle and shoot poison arrow hairs at what they sense is an odd intruder.

    I know it wasn't in Carl's nature (and I wish it was in no one's nature), but unfortunately, once you get to the socio-economic / political conditions the USA is now in (2023), where the top 10% essentially own the whole country, where the three richest billionaires in the USA have the same net worth as the bottom 50% of the population (164 million people), where corruption has rotted every facet of the government, at every level, including fascist (read: Nazi) billionaires OWNING at least two supreme court justices, and one of them for decades, the use of guillotines of those in power and their descendants is the only way forward. Consider that the conditions that led to the Declaration of Independence in 1776 where a walk in the park on a sunny afternoon eating ice cream compared to the dystopian third-world country the USA is now.
