The paper
Abstract
The bulk viscosity is calculated for hadron matter produced in heavy-ion collisions, being described in the relaxation time approximation withi n the relativistic mean- field-based model with scaled hadron masses and couplings. W e show how different approximations used in the literature affect the result. Nume rical evaluations of the bulk viscosity with three considered models deviate not much from each other confirming earlier results.

At high temperature the mean-field effects are less pronounced and the values for the bulk viscosity of partonic matter from PHSD are approaching those obtained in the scope of the SHMC-HQB model [ref] .

Comparing our results with those computed recently in the linear sigma model [ref] in the crossover region (line with circles in the figure) one may see an overall agreement, although models as well as final expressions used for the bulk viscosities are essentially different.

Recently, interest in the transport coefficient issue for hadronic and quark matter has essentially increased due to clarifying the role of viscosity in extraction of flow parameters from heavy-ion collisions, see review-article [ref] .
