Kanako Yamazaki (University of Tokyo)07/08/2014, 16:00parallelWe study the QCD phase transition by a Nambu-Jona-Lasinio model extended with the Polyakov loop. This model was proposed by combining the Nambu-Jana-Lasinio model which describes the chiral transition and the Polyakov loop which works as an order parameter of de-confinement transition. The aim of this work is to describe the change of degrees of freedom from hadrons to quarks through the...Go to contribution page

Kenji Morita07/08/2014, 16:20parallelWe discuss feasibility of detecting the QCD phase boundary using Lee-Yang zero from the net baryon number multiplicity distributions. Since only limited number of net proton can be measured in heavy ion collisions, the canonical partition function extracted from the multiplicity distribution loses information stored in the tail of the distribution. By using a random matrix model, we...Go to contribution page

Ms Miki Sakaida (Osaka University)07/08/2014, 16:40parallelWe investigate the effects of the global charge conservation on the rapidity window dependences of fluctuations of conserved charges observed in heavy ion collisions by solving the diffusion master equation with boundaries. Our result suggests that the effects of the global charge conservation for the diffusion in the hadronic phase is negligible in the experimental results even with the...Go to contribution page

Akio TOMIYA (Osaka university)07/08/2014, 17:00parallelWe investigate the issue of possible restoration of the axial U(1) symmetry at finite temperature, using lattice simulations with the Mobius domain-wall fermion. In this talk, we focus on the effects of near-zero Dirac eigenmodes, which play a crucial role for both SU(2)xSU(2) chiral symmetry restoration and the restoration/breaking of axial U(1) symmetry. Performing simulations at two...Go to contribution page
