Dynamical quasiparticles properties and effective interactions in the sQGP

Abstract: Dynamical quasiparticle properties are determined from lattice QCD along the line of the Peshier model for the running strong coupling constant in case of three light flavors. By separating time-like and space-like quantities in the number density and energy density the effective degrees of freedom in the gluon and quark sector may be specified from the time-like densities. The space-like parts of the energy densities are identified with interaction energy (or potential energy) densities. By using the timelike… Show more

“…This opens up the problem how to interpret/deal with the space-like part of the distribution functions and how to 'propagate' effective degrees in space-time in equilibrium as well as out of equilibrium without violating 'microcausality'. These questions will now be addressed in the Dynamical QuasiParticle Model (DQPM) [121].…”

“…[68,71]). Furthermore, the spectral distribution for the mass of the quasiparticle has a finite pole mass M q (T, µ q ) that is also fixed in the DQPM, as well as the density of (u,ū, d,d, s,s) quarks/antiquarks as a function of temperature and chemical potential (cf.…”

“…There are various models which can be used to study the region near T c , which we call the "semi" Quark-Gluon Plasma. This includes Parton Hadron String Dynamics [50][51][52][53][54][55], Polyakov loop models [56][57][58], the functional renormalization group [59][60][61][62][63][64][65][66][67][68][69][70], background field methods [71][72][73], and lastly, matrix models [74][75][76][77][78][79][80][81][82][83][84][85].…”
