Transport properties of hadronic matter in magnetic field

Abstract

We study the effect of magnetic field on the transport properties like shear and bulk viscosities of hot and dense hadronic matter within hadron resonance gas model. We estimate the bulk viscosity using low energy theorems for bilocal correlators of the energy momentum tensor generalized to finite temperature, density and magnetic field. We use Gaussian ansatz for the spectral function at low frequency. We estimate shear viscosity coefficient using molecular kinetic theory. We find that vacuum contribution due to finite magnetic field dominates the bulk viscosity ({\zeta}) for the temperatures up to 0.1GeV and increases with magnetic field while ratio {\zeta}/s decreases with magnetic field. We also find that shear viscosity coefficient of hadronic matter decreases with magnetic field.
