The Nobel Prize in Physics 2013 Announced

The Nobel Prize in Physics 2013 was awarded jointly to

François François Englert (Born: 1932
Peter W. Higgs
Peter W. Higgs (Born: 1929)
Englert and Peter W. Higgs “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider”

François Englert and Peter W. Higgs are jointly awarded the Nobel Prize in Physics 2013 for the theory of how particles acquire mass. In 1964, they proposed the theory independently of each other (Englert together with his now deceased colleague Robert Brout). In 2012, their ideas were confirmed by the discovery of a so called Higgs particle at the CERN laboratory outside Geneva in Switzerland..

The awarded theory is a central part of the Standard Model of particle physics that describes how the world is constructed. According to the Standard Model, everything, from flowers and people to stars and planets, consists of just a few building blocks: matter particles. These particles are governed by forces mediated by force particles that make sure everything works as it should.

The entire Standard Model also rests on the existence of a special kind of particle: the Higgs particle. This particle originates from an invisible field that fills up all space. Even when the universe seems empty this field is there. Without it, we would not exist, because it is from contact with the field that particles acquire mass. The theory proposed by Englert and Higgs describes this process.

On 4 July 2012, at the CERN laboratory for particle physics, the theory was confirmed by the discovery of a Higgs particle. CERN’s particle collider, LHC (Large Hadron Collider), is probably the largest and the most complex machine ever constructed by humans. Two research groups of some 3,000 scientists each, ATLAS and CMS, managed to extract the Higgs particle from billions of particle collisions in the LHC.

Even though it is a great achievement to have found the Higgs particle — the missing piece in the Standard Model puzzle — the Standard Model is not the final piece in the cosmic puzzle. One of the reasons for this is that the Standard Model treats certain particles, neutrinos, as being virtually massless, whereas recent studies show that they actually do have mass. Another reason is that the model only describes visible matter, which only accounts for one fifth of all matter in the cosmos. To find the mysterious dark matter is one of the objectives as scientists continue the chase of unknown particles at CERN.

Gauge Theory and Higgs Mechanism

What is Gauge Theory and how does it relate to electroweak symmetry? How does the breaking of a symmetry cause a reaction such as the obtaining of mass?

 

Asked Markus

 

English: An overview of particle physics

 

In particle physics, the Higgs mechanism is a kind of mass generation mechanism, a process that gives mass to elementary particles.

Particle and Field

Is it necessary that particles should be present for the presence of a any field ?for example in higgs field,  higgs boson are the particles which are responsible for it.

Asked Sandeep

Work done in accelerating a proton

The mass of a proton is 1840 times that of an electron. it is accelerated to a potential difference of 1kV. find the amount of work done in process. (Ujjwal Sharma asked)

Answer

The work done = the KE acquired = eV=1.6 x 10-19 x 1000 = 1.6 x 10-16 J

What is gravity?

The Feynman diagram en for the beta-negative d...

So I’ve been thinking about what gravity really is, I know it’s a rather weak force, but dominates the universe.  Is there a possibilities that gravity is actually inter-molecular forces?
