Copy of GOD PARTICLE
Transcript of Copy of GOD PARTICLE
The Higgs mechanism is the simplest way to explain how certain elementary particles have mass.
Particles acquire mass by interacting with this Higgs field, which has non-zero strength everywhere .
Large Hadron Collider (LHC) at CERN in Geneva, Switzerland—the most powerful particle accelerator and one of the most complicated scientific instruments was built to test the existence of the Higgs boson and measure its properties.
It is named for Peter Higgs who, along with two other teams, proposed the mechanism that suggested such a particle in 1964.
It is very often referred to as "the God particle".
According to the Standard Model, the Higgs particle is a boson, a type of particle that allows multiple identical particles to exist in the same place in the same quantum state. HIGGS BOSON THE DISCOVERER - PETER HIGGS STANDARD MODEL WAY TO DISCOVERY ABOUT THE GOD PARTICLE

-> Broken symmetry in electroweak theory
-> Higgs boson
-> Higgs field
-> Higgs mechanism THE MASTER MIND
: Gauge bosons
: Higgs boson WAY TO DISCOVERY HIGGS BOSON PROPERTIES The Standard Model predicts the existence of a field, called the Higgs field, which has a non-zero amplitude in its ground state; i.e. a non-zero vacuum expectation value. In the Standard Model, the Higgs field consists of four components, two neutral ones and two charged component fields. Both of the charged components and one of the neutral fields are Goldstone bosons, which act as the longitudinal third-polarization components of the massive W+, W–, and Z bosons. Since the Higgs field is a scalar field, the The Higgs boson is also its own antiparticle and is CP-even, and has zero electric and colour charge. It helps to predict masses of different elements IMPORTANCE The theory of the big bang 13.7 billion years ago will be challenged as more understanding is made of the findings of the Higgs boson. The big bang theory presupposes that space and time are finite, whereas it is more likely they are both infinite. The theory does not explain what was the nature of the universe before the big bang. It also does not explain that, in all probability, no matter how far you travel into the universe, you will never come to the end. One possible signature of a Higgs boson from a simulated proton–proton collision. It decays almost immediately into two jets of hadrons and two electrons, visible as lines. HARI- OM FACTS ABOUT THE GOD PARTICLE After 45 of struggling research involving millions of dollars, CERN has finally proved it’s existence. But how does it matter to us? It can solve the mysteries of the universe. A new atomic model to explain the big bang and formation of mass can be build up. It was initially proposed by Peter Higgs in 1964, after whom the God particle was named. After 45 years of research and countless experiments at CERN Hadron Collider, the existence is now discovered by the team of physicists and every member associated. It will shed light on one of the unsolved mysteries of the Universe and the creation of matter, the emergence of mass. Higgs boson has no spin.This puts it in a class of particles known as the 'BOSONS' These particles obey the Bose - Einstein statistics first discovered by Indian physicist Satyendranath Bose. Hence the word BOSON. DESCRIPTION It is also very unstable, decaying into other particles almost immediately. THE STANDARD MODEL The existence of the Higgs boson was predicted in 1964 to explain the Higgs mechanism. While the Higgs mechanism is considered confirmed to exist, the boson itself—a cornerstone of the leading theory—had not been observed and its existence was unconfirmed. Its tentative discovery in July 2012 may validate the Standard Model as essentially correct, as it is the final elementary particle predicted and required by the Standard Model which had not yet been observed via particle physics experiments Alternative sources of the Higgs mechanism that do not need the Higgs boson also are possible and would be considered if the existence of the Higgs boson were to be ruled out. They are known as Higgsless models. Experiments to confirm and determine the nature of the Higgs boson using the Large Hadron Collider (LHC) at CERN began in early 2010, and were performed at Fermilab's Tevatron until its close in late 2011 It is of mass between 125–127 GeV/c2. The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the European Organization for Nuclear Research (CERN) from 1998 to 2008, with the aim of allowing physicists to test the predictions of different theory of particle physics and high-energy physics, and particularly that of the existence of the hypothesized Higgs boson. Quest for Higgs boson is 40 years young
Most likely, discovery and initial characterization awaits the LHC
Life may well be much more interesting than the simplest Standard Model Higgs! CONCLUSION PARTICLE? A: Imagine a crowd of people in a room. This is like the higgs field. Suddenly a filmstar enters the room.People cluster around her thereby her progress gets slower.It is as though she has gained mass. It is same as a particle moving through the higgs field and gaining mass. EXPLAIN THE MECHANISM BY WHICH THE HIGGS FIELD GIVES MASS TO OTHER PARTICLES. Q. How does the higgs itself get a mass?
A. Imagine a room full of people - this is like the higgs field. What if a rumour starts among them? As the rumour goes from person to person, there is an automatic clustering around the speaker. This clustering is like a particle with mass. This is how higgs gets its mass. NIMISHA HONNALLI PRESENTED BY- ytrr ... small PRATIKSHA PAI REEYA RAYKAR UNNATI BABRUWAD PARTICLE ACCELERATOR The Standard Model falls short of being a complete theory of fundamental interactions because it does not incorporate the physics of dark energy nor of the full theory of gravitation as described by general relativity. The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known sub atomic particles. SOME IMAGES OF CERN Nevertheless, the Standard Model is important to theoretical and experimental particle physicists alike. PETER HIGGS FACTS ABOUT THE HIGGS BOSON INDIA'S CONTRIBUTION TO THE HIGGS It completes the set of predicted particles in the Standard Model. WHAT WOULD THE WORLD LOOK LIKE WITHOUT THE HIGGS BOSON OR A SIMILAR PARTICLE?
A: You wouldn’t recognize the world. Without the Higgs boson or something like it giving mass to the basic building blocks of matter, electrons would zip about at the speed of light. They would not form unions with protons or other would-be nuclei to make atoms. No atoms means no chemical reactions, no molecules, no ordinary matter as we know it, no template for life. We would not exist. WHICH COUNTRIES ARE INCLUDED IN THE TEVATRON'S CDF AND D-ZERO EXPERIMENTS?
A: CDF: Canada, Finland, France, Germany, Greece, Italy, Japan, Korea, Russia, Slovakia,Spain, Switzerland, Taiwan, the United Kingdom and the United States.
DZero: Brazil, China, Colombia, Czech Republic, Ecuador, France, Germany,India, Ireland, Korea, Mexico, the Netherlands, Russia, Spain,
Sweden, Ukraine, the United Kingdom and the United States. HOW DO PHYSICISTS CREATE A HIGGS BOSON?
A: A high-energy particle accelerator such as the Tevatron or LHC can recreate the extreme energies of the very early universe, generated shortly after the Big Bang. Scientists collide particles at these energies to produce other particles, including a Higgs boson, using Einstein’s famous relation E=mc2. At the Tevatron or LHC, only about one collision per trillion will produce a Higgs boson. Notable awards:-
->Wolf Prize in Physics (2004)
->Sakurai Prize (2010)
->Dirac Medal (1997) The discovery of a new elementary sub atomic particle has a strong connection with the Indian scientists. The discovery has an emotional link with India, with legendary Indian physicist Satyendranath Bose after whom the particle gets the latter part of its name (BOSON). India's actual contribution to the LHC began in 1996 when the department of atomic energy signed a protocol with CERN to contribute for the LHC. Over the years India provided some of the key equipment and systems needed in constructing LHC,including superconducting magnets, engineering components for electronics and control systems. INDIA'S CONTRIBUTION TO THE HIGGS More than two decades. It started with the LEP experiments at CERN in the 1990s, continued with the Tevatron experiments at Fermilab and now continues with the Large Hadron Collider (LHC) experiments at CERN. A discovery of the Higgs boson would be just the beginning of a new era of particle physics research. Scientists would then focus on understanding in detail the interactions of the Higgs boson with other particles, testing the predictions made by theorists and looking for unexpected phenomena.
