Highly succesful heavy-ion run

The second heavy ion run with lead+lead collisions at E=2.76 TeV per nucleon pair took place in november-december 2011. The run was highly sucessful.

The peak luminosity delivered by the LHC exceeded the design values by a factor of 3 and the total recorded number of collisions was aboutt a factor of 10 higher that the first heavy ion which took place in 2010.  This bodes well for the physics analysis, which will in particular focus on the role of heavy quarks in the quark-gluon-plasma(QGP) and the transport properties of the QGP.
