Superdense Primordial Soup: Heavy Flavor Tracker At Brookhaven And Quark-Gluon Plasma

Microseconds after the big ban happened the universe was a superhot, superdense primordial soup of “quarks” and “gluons,” particles of matter and carriers of force. The quark-gluon plasma cooled almost instantly but it set the stage for the universe we kno ...

More Confirmations On Y(4140) And Y(4270) From BaBar

The Y(4140) state, a resonance found in decays of the B meson to J/ψ φ K final states, is the protagonist of a long saga. Originally it was obseved by CDF in 4 inverse femtobarns of Run 2 data by Kai Yi, a very active "bump hunter" in the experim ...

Death Of The Dijet Anomaly

Do you remember the CDF Dijet bump at 145 GeV? In 2010, CDF published a paper that showed how the same data sample of W + jet events where they had previously isolated the "single-lepton" WW+WZ signal also presented an intriguing excess of events ...

Top Asymmetry: The Latest From DZERO

It is nice to see that the Tevatron experiments are continuing to produce excellent scientific measurements well after the demise of the detectors. Of course the CDF and DZERO collaborations have shrunk in size and in available man-years for data analysis ...

Dreaming Of Tau Lepton Decays

The tau lepton is a particle of very complex phenomenology. Although point-like as its lighter counterparts- the electron and the muon- the tau has a quite respectable mass, 1.77 GeV, which makes all the difference from the other charged leptons. The tau w ...
