Quasiparticle theory of shear and bulk viscosities of hadronic matter

P Chakraborty, JI Kapusta - Physical Review C—Nuclear Physics, 2011 - APS
A theoretical framework for the calculation of shear and bulk viscosities of hadronic matter at
finite temperature is presented. The framework is based on the quasiparticle picture. It …

Shear viscosity of a hadron gas and influence of resonance lifetimes on relaxation time

JB Rose, JM Torres-Rincon, A Schäfer… - Physical Review C, 2018 - APS
We address a discrepancy between different computations of η/s (shear viscosity over
entropy density) of hadronic matter. Substantial deviations of this coefficient are found …

Bulk viscosity in quasiparticle models

C Sasaki, K Redlich - Physical Review C—Nuclear Physics, 2009 - APS
We discuss transport properties of dynamical fluid composed of quasiparticles whose
masses depend on temperature and charge chemical potentials. Based on the relativistic …

Transport coefficients near chiral phase transition

C Sasaki, K Redlich - Nuclear Physics A, 2010 - Elsevier
We analyze the transport properties of relativistic fluid composed of constituent quarks at
finite temperature and density. We focus on the shear and bulk viscosities and study their …

Transport coefficients and resonances for a meson gas in Chiral Perturbation Theory

D Fernández-Fraile, A Gomez Nicola - The European Physical Journal C, 2009 - Springer
We present recent results on a systematic method to calculate transport coefficients for a
meson gas (in particular, we analyze a pion gas) at low temperatures in the context of Chiral …

Viscosity in the excluded volume hadron gas model

MI Gorenstein, M Hauer, ON Moroz - Physical Review C—Nuclear Physics, 2008 - APS
The shear viscosity η in the van der Waals excluded volume hadron-resonance gas model is
considered. For the shear viscosity the result of a nonrelativistic gas of hard-core particles is …

Suppression of the shear viscosity in a “semi”-quark-gluon plasma

Y Hidaka, RD Pisarski - Physical Review D—Particles, Fields, Gravitation, and …, 2008 - APS
We consider QCD at temperatures T near T c, where the theory deconfines. We distinguish
between a “complete” quark-gluon plasma (QGP), where the vacuum expectation value of …

Shear viscosity of a hadronic gas mixture

K Itakura, O Morimatsu, H Otomo - Physical Review D—Particles, Fields …, 2008 - APS
We discuss in detail the shear viscosity coefficient η and the viscosity to entropy density ratio
η/s of a hadronic gas comprised of pions and nucleons. In particular, we study the effects of …

Electrical conductivity of a pion gas

D Fernández-Fraile, AG Nicola - … Review D—Particles, Fields, Gravitation, and …, 2006 - APS
The electrical conductivity of a pion gas at low temperatures is studied in the framework of
linear response and chiral perturbation theory. The standard ChPT power counting has to be …

QCD viscosity to entropy density ratio in the hadronic phase

JW Chen, YH Li, YF Liu, E Nakano - Physical Review D—Particles, Fields …, 2007 - APS
The shear viscosity η of QCD in the hadronic phase is computed by the coupled Boltzmann
equations of pions and nucleons in low temperatures and low baryon-number densities. The …
