Higgs Discovery Explained - Ep. 1/3 | CERN

What is the Higgs Boson, and why is it important?

In 2012, the Higgs boson was discovered. In 2013, the scientists received the Nobel Prize in Physics for the mathematical formulation. But, what is this boson, and why is it important?
Just watch the video:

The Higgs Boson and Our Life

On July 4th, 2012, the ATLAS and CMS experiments operating at the CERN Large Hadron Collider (LHC) announced the discovery of a new particle compatible with the Higgs boson (hunted for almost 50 years), which is a crucial piece for our understanding of fundamental physics and thus the structure and evolution of the universe. This lecture describes the unprecedented instruments and challenges that have allowed such an accomplishment, the meaning and relevance of this discovery to physics, and the implications to our day to day lives.

Time to say goodbye to 2012 with the biggest scientific new this year.
I wish you a happy 2013.

Latest news about Higgs Boson

(Phys.org) -- The two teams working (and causing headlines around the world) at the CERN Large Hadron Collider CMS and ATLAS, have both uploaded papers describing their work in searching for evidence of the particle that is believed to explain why matter sticks together, the elusive Higgs Boson, to the preprint server arXiv. In their paper, ATLAS has bumped up its sigma level of certainty from 5.0 to 5.9 while CMS has kept its level at the 4.9 to 5 range.

(Fermilab Today) -- The month of July 2012 is bound to be remembered as the crescendo of the summer of the Higgs boson. It began with the announcement of results from the Tevatron's search for the Standard Model Higgs boson, followed immediately by reports of the observation of a new particle by the LHC experiments. As the month continued, the CDF and DZero experiments released 10 publications on Higgs searches in multiple decay channels, building the pillars of the Tevatron's search for the Higgs boson in the state most difficult to pursue at the LHC, the Higgs boson decaying into two bottom quarks. Last week ended with the submission of the keystone paper in that combined effort, in which CDF and DZero announce finding evidence of a particle in the bottom quark pair search channel.

The Higgs Boson - Part 1 & 2

The Higgs Boson explained

The world of particles is very attractive to physicist. I written several posts about it.
But, PHD Comics made a simple video that explain all of it and how LHC tray to find Higgs Boson. Watch it:

Dissecting the Pinguin

Flip Tanedo wrote a great post about one of the amusing tales in particle physics: The story of how the “penguin diagram” got its name. Taneda won’t go into that in his post, instead, he will make use of some of the tools developed with Feynman diagrams to understand the physics behind these ‘penguin’ diagrams. In doing so, he will have a nice playground to really make use of what we’ve learned so far about Feynman rules. (Feel free to review the series if you need a refresher!)

Measurement of W boson mass tests Standard Model, Higgs boson limits

The new CDF result for the W boson mass, combined with the world's best value for the top quark mass, restricts the Higgs mass to the green area, requiring it to be less than 145 GeV/c2. Direct searches have narrowed the allowed Higgs mass range to 115-127 GeV/c2.

(PhysOrg.com) -- Just as firemen use different methods to narrow the location of a person trapped in a building, scientists employ two techniques to find the hiding place of the theorized Higgs particle: direct searches for Higgs interactions and precision measurements of other particles and forces.

Higgs, the God particle

Need to know more about the Higgs Boson (particle that carries the mass)?

The Higgs boson (sometimes nicknamed the "God particle" in popular media) is a hypothetical massive elementary particle that is predicted to exist by the Standard Model (SM) of particle physics. The Higgs boson is an integral part of the theoretical Higgs mechanism. If shown to exist, it would help explain why other particles can have mass. It is the only predicted elementary particle that has not yet been observed in particle physics experiments. Theories that do not need the Higgs boson also exist and would be considered if the existence of the Higgs Boson was ruled out. They are described as Higgsless models.

If shown to exist, the Higgs mechanism would also explain why the W and Z bosons, which mediate weak interactions, are massive whereas the related photon, which mediates electromagnetism, is massless. The Higgs boson is expected to be in a class of particles known asscalar bosons. (Bosons are particles with integer spin, and scalar bosons have spin 0.)

Experiments attempting to find the particle are currently being performed using the Large Hadron Collider (LHC) at CERN, and were performed at Fermilab's Tevatron until its closure in late 2011. Some theories suggest that any mechanism capable of generating the masses of elementary particles must be visible at energies below 1.4 TeV; therefore, the LHC is expected to be able to provide experimental evidence of the existence or non-existence of the Higgs boson.
