Bose-Einstein Interferences: The Collider View

One of the few physics measurements that the LHC experiments are already in the position of producing, with the week-worth of proton-proton collision data they have collected last December, is that of the Bose-Einstein intereference between identical boson ...

Big Bang, Big Bewilderment

We live in an expanding universe. Distant galaxies move away from us, and these galaxies see us moving away from them. If we reverse time and trace back this expansion, it follows that the universe has evolved from a dense primeval/primordial state. The b ...

T2K And The 'Ghosts' Of Particle Physics

The T2K (Tokai-to-Kamioka) project has tracked their first neutrino, one of the least understood particles in the universe.  The detection of the neutrino as it passed 185 miles from the East to the West of Japan means the study of the mysterious phenomeno ...

The Quote of the Week

"We were not yet prepared to claim that we had found a new charged lepton, but we were ready to claim that we had found something new. To accentuate our uncertainty I denoted the new particle by U for unknown in some of our 1975-1977 papers. The name ...

CDF On Higgs Decays To Diphotons

The CDF collaboration has recently released new results from a search for what is probably the clearest signature of Higgs boson decay: pairs of high-mass photon candidates. I am very glad to see this new analysis out for publication, since so far only DZE ...

Understanding Muon Decay

Yesterday somebody asked me here if I could explain how does a muon really decide when and how to decay. I tried to answer this question succintly in the thread, and later realized that my answer, although not perfectly correct in the physics, was actually ...

All Women Team Runs The CMS Experiment On March 8th

On March 8th, international women day, the CMS experiment at CERN will be run almost entirely by women. 32 of the 34 shifts needed to run our experiment will be covered by women scientists of our Collaboration- which counts 588 women overall. I think this ...

Ten Thousand Internal Documents

The CDF collaboration, which runs one of the two proton-antiproton collider experiments at the Fermi National Accelerator Laboratory since the early eighties, has published hundreds of scienticif papers in the course of its 25 years of operation. I believe ...
