Curious minds might wonder why the LHC, which successfully ran at 7 TeV during the pp run of 2010 began the new year with proton collisions at a significantly less energy of 2.76 TeV. The fact is that this lower energy allowed experiments such as...

In our Universe today, quarks are always bound together by gluons to form "composite" particles such as protons and neutrons. The Quark-Gluon Plasma, or QGP, often described as a soup-like medium, is a hot, dense state in which these quarks and...
