"Thermal Quark and Gluon Distributions in the PNJL model"

Presented by Hung-Ming Tsai, Duke University

Friday, December 3, 2010, 2:00 pm — Small Seminar Room, Bldg. 510

In this talk, we explore the dynamics of gluons in the Nambu-Jona-Lasinio model with Polyakov loop (PNJL model) within the mean-field approximation. We first calculate the fundamental Polyakov loop by minimizing the PNJL action and then obtain the adjoint Polyakov loop by demanding self-consistency with the Gocksch-Ogilvie effective action for the eigenvalues of the Polyakov loop. We then derive the quark and gluon number densities and other thermodynamic quantities as functions of temperature and chemical potential. We explain why the deconfinement transition is much faster for light quarks than for gluons
