Landau gauge gluon and ghost propagators from lattice QCD with $N_f$=2 twisted mass fermions at finite temperature

Hadronic matter may experience a phase transition or crossover from a confined phase, with broken chiral symmetry, to a deconfined chirally symmetric phase. The latter phase is characterized by a state called quark gluon plasma. It is widely believed this state of matter has been passed in the early universe, and efforts are undertaken to reproduce it experimentally in heavy-ion collisions as in present collider experiments at RHIC (BNL) or with the ALICE and CMS detectors at LHC (CERN).
