Rasmus Larsen (Stony Brook University)28/09/2015, 11:15QCD at High TemperatureContributed talkInstantons for a long time were associated with breaking of U(1) and SU(Nf) chiral symmetries in QCD-like theories. Monopoles, on the other hand are related to dual superconductor picture and confinement. Instanton-dyons are instanton constituents, discovered in 1998 by van Baal and others: they incorporate properties of both instants and monopoles. Recently several papers, both analytic...Go to contribution page

Dr Sayantan Sharma (BNL)28/09/2015, 11:35QCD at High TemperatureContributed talkThe nature of chiral phase transition for two flavour QCD is an interesting but unresolved problem. One of the most intriguing issues is whether or not the anomalous U(1) symmetry in the flavour sector is effectively restored along with the chiral symmetry. This may determine the universality class of the chiral phase transition. Since the physics near the chiral phase transition is...Go to contribution page

Szabolcs Borsanyi (University of Wuppertal)28/09/2015, 11:55QCD at High TemperatureContributed talkWe extrapolate the QCD cross-over temperature from imaginary to real chemical potentials. Our calculations are based on new continuum extrapolated lattice simulations using the 4stout staggered actions with a lattice resulution up to Nt=16. The simulation parameters are tuned so that the strangeness neutrality is maintained, as it is in a heavy ion collision. We see a consistency between...Go to contribution page

Dr Jacopo Ghiglieri (Universitaet Bern (CH))28/09/2015, 12:15QCD at High TemperatureContributed talkWe present a set of kinetic equations which extend the AMY energy loss formalism to NLO in the strong coupling constant. A novel aspect of the NLO analysis is a consistent description of wider-angle bremsstrahlung (semi-collinear emissions) which smoothly interpolates between 2to2 scattering and collinear bremsstrahlung. Similarly, the NLO treatment describes how the soft collinear emissions...Go to contribution page

Alexander Philipp Kalweit (CERN)28/09/2015, 12:35QCD at High TemperatureContributed talkWe construct net baryon number and strangeness susceptibilities as well as correlations between electric charge, strangeness and baryon number from experimental data on the particle production yields at midrapidity of the ALICE Collaboration at CERN. The data were taken in central Pb-Pb collisions at √sNN=2.76 TeV and cover one unit of rapidity. The resulting fluctuations and correlations are...Go to contribution page
