67. Search for critical point indications in long-range correlations by energy and system size scanning in string fusion approach

Section D: Deconfinement

Studies of the collisions of various hadrons and nuclei at different centrality and energy enable to explore the QCD phase diagram over a wide range of temperature and baryon density in search of the critical point. In the framework of the string fusion approach [1] the critical behavior takes place when the processes of string fusion and percolation come into play, what can be considered as a...

69. Dynamical locking of the chiral and the deconfinement phase transition in QCD at finite chemical and isospin chemical potential

Section D: Deconfinement

Studies of the QCD phase diagram at finite temperature and quark chemical potential are currently one of the most discussed topics in theoretical physics and are of great importance to better our understanding of heavy-ion collision experiments. However, the relation of confining and chiral dynamics is not yet completely understood. At vanishing chemical potential, results from lattice QCD...

73. The critical end point through observables

Prof. Gennady Kozlov (JINR)

Section D: Deconfinement

The critical phenomena of strongly interacting matter are presented in the frame of an effective theory at finite temperatures. The phase transitions are considered in systems where the critical end point (CEP) is a distinct singular feature existence of which is dictated by the chiral dynamics. The physical approach to the effective CEP is studied via the influence fluctuations of...

101. Deconfinement transition in a massive extension of the background field gauge

Matthieu Tissier (Univ. P. and M. Curie)

Section D: Deconfinement

We discuss the breaking of center symmetry in pure SU(2) and SU(3) Yang-Mills theories at finite temperature. We explore this question using a perturbative approach within a massive extension of the background field gauge which is seen as a phenomenological way of taking into account the effect of the Gribov copies. At one-loop order, this simple perturbative calculation yields a second order...

141. Two-color QCD with chiral chemical potential

Andrey Kotov (ITEP)

Section D: Deconfinement

We present preliminary results of the study lattice SU(2) QCD phase diagram with chiral chemical potential. The simulation is carried out with dynamical staggered fermions without rooting. The dependences of the chiral density, Polyakov loop, chiral condensate and corresponding susceptibilities on the chiral chemical potential and temperature are measured.

198. 2-color QCD at High Density

Section D: Deconfinement

QCD at high chemical potential has interesting properties such as deconfinement of quarks. 2-color QCD, which enables numerical simulations on the lattice, constitutes a laboratory to study QCD at high chemical potential. The quark propagator in 2-color QCD at high density is referred to as the Gorkov propagator. We examine the Gorkov propagator and in particular, find the form factors of the...
