Quark-meson-diquark model for two-color QCD

Nils Strodthoff, Bernd-Jochen Schaefer, Lorenz von Smekal

We introduce a two-flavor quark-meson-diquark model for two-color QCD and its extensions to include gauge-field dynamics as described by the Polakov loop. Grand potential and phase…

Net-charge probability distributions in heavy ion collisions at chemical freeze-out

P. Braun-Munzinger, B. Friman, F. Karsch +2

We explore net charge probability distributions in heavy ion collisions within the hadron resonance gas model. The distributions for strangeness, electric charge and baryon number…

Transport Properties of Strong-Interaction Matter

J. Wambach, K. Heckmann, M. Buballa

The properties of strong-interaction matter are probed in ultra-relativistic heavy-ion collisions. In the context of measurements of the elliptic flow at RHIC and the LHC the shear…

Out of equilibrium dynamics of coherent non-abelian gauge fields

J. Berges, S. Scheffler, S. Schlichting +1

We study out-of-equilibrium dynamics of intense non-abelian gauge fields. Generalizing the well-known Nielsen-Olesen instabilities for constant initial color-magnetic fields, we in…

Net-proton probability distribution in heavy ion collisions

P. Braun-Munzinger, B. Friman, F. Karsch +2

We compute net-proton probability distributions in heavy ion collisions within the hadron resonance gas model. The model results are compared with data taken by the STAR Collaborat…

Particle Production in p-p and Heavy Ion Collisions at Ultrarelativistic Energies

J. Cleymans, S. Kabana, I. Kraus +3

Recent results related to the chemical equilibration of hadrons in the final state of p-p and heavy ion collisions are reviewed.

On critical scaling at the QCD N_f=2 chiral phase transition

Christian S. Fischer, Jens A. Mueller

We investigate the critical scaling of the quark propagator of N_f=2 QCD close to the chiral phase transition at finite temperature. We argue that it is mandatory to take into acco…

Antimatter production in proton-proton and heavy-ion collisions at ultrarelativistic energies

J. Cleymans, S. Kabana, I. Kraus +3

One of the striking features of particle production at high beam energies is the near equal abundance of matter and antimatter in the central rapidity region. In this paper we stud…

Analysis of matter suppression in collective neutrino oscillations during the supernova accretion phase

Sovan Chakraborty, Tobias Fischer, Alessandro Mirizzi +2

The usual description of self-induced neutrino flavor conversions in core collapse supernovae (SNe) is based on the dominance of the neutrino density n_nu over the net electron den…

No collective neutrino flavor conversions during the supernova accretion phase

Sovan Chakraborty, Tobias Fischer, Alessandro Mirizzi +2

The large neutrino fluxes emitted with a distinct flavor hierarchy from core-collapse supernovae (SNe) during the post-bounce accretion phase, offer the best opportunity to detect…

Chiral and deconfinement phase transitions of two-flavour QCD at finite temperature and chemical potential

Christian S. Fischer, Jan Luecker, Jens A. Mueller

We present results for the chiral and deconfinement transition of two flavor QCD at finite temperature and chemical potential. To this end we study the quark condensate and its dua…

Recent Theoretical Developments in the QCD Phase Diagram

Jochen Wambach

In this talk I discuss three recent developments in the theoretical understanding of the phase diagram of the strong interaction. The first topic deals with the comparison of model…
