The CMS collaboration is presenting its latest results this week at the annual Quark Matter conference, held this year in Annecy, France.
The CMS experiment has made several unique measurements using data from LHC collisions of lead nuclei (PbPb, November 2010) at centre-of-mass energies of 2.76 TeV per nucleon pair.
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 gluons exist freely, unbound.
The paper, accepted for publication in Physical Review D in April, presents the first measurement of Υ (Upsilon) production at a centre-of-mass collision energy of 7 TeV at the LHC.
Maurizio Pierini has been with CMS since he first started work at CERN in 2007. He tells us about his work, his interests, and why physics is such a big part of his life.
