Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a Universe of matter, with very little antimatter, remains a myster...
If you asked the average Pennsylvanian why they were celebrating the 4th of July this year, they would probably tell you that it was to mark Independence Day.
Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
The Higgs boson lives for an extremely short time before it transforms, or “decays”, into other particles. It is through the detection of some of these decay products that the unique particle has firs...

The Higgs boson doesn’t stick around for long. Once it is created in particle collisions, the famed particle lives for a mere less than a trillionth of a billionth of a second or, more precisely, 1.6 ...

"International Symposium on Higgs Boson and Beyond Standard Model Physics" aims at updating our understanding of Higgs boson physics in the Standard Model & beyond, addressing the recent progress on t...
Higgs boson mass bounds in the presence of a very heavy fourth quark generation
Higgs boson mass bounds quark generation

Comment on "New constraints of a light CP-odd Higgs boson and related NMSSM Ideal Higgs Scenarios" by Dermisek and Gunion (arXiv:1002.1971 [hep-ph])
light CP-odd Higgs boson NMSSM Ideal Higgs
2010/3/16
In two recent papers (arXiv:1002.1971 [hep-ph] and arXiv:0911.2460 [hep-ph]) Dermisek and Gunion provide new constraints on a light CP-odd Higgs boson in the framework of the NMSSM (or similar models)...
Search for a Low Mass Standard Model Higgs Boson at D0 in ppbar Collisions at $\sqrt{s}=1.96 TeV$
Low Mass Standard Model $\sqrt{s}=1.96 TeV$ center-of-mass energy
2010/3/15
We present combined searches for the Low Mass Standard Model Higgs boson at a center-of-mass energy of $\sqrt{s}=$1.96 TeV, using up to 5 fb$^{-1}$ of data collected with the D0 detector at the Fermil...
