During the evolution of the early universe, about one microsecond after the Big Bang, the universe consisted of mainly free quarks and gluons, commonly referred to as a quark-gluon plasma (QGP). The recreation and study, via relativistic heavy-ion collisions, of this form of matter has been one of the primary goals of the nuclear physics community in the last decades. At the Large Hadron Collider (LHC) a new era has started at the end of 2010, when the first heavy ions were collided with an energy never reached before. I will present results from data registered by the CMS detector during the first PbPb run at √s_NN=2.7 6TeV, the first steps towards a detailed characterization of the QGP properties in a new and unexplored energy regime.
