Instantons 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...

The 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...

We 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...

We 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...

We 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...
