## TL;DR

This paper calculates shear and bulk viscosities and electrical conductivity of quark and hadronic matter using the Polyakov-Quark-Meson model, focusing on thermal widths derived from self-energies at finite temperature.

## Contribution

It provides a detailed evaluation of transport coefficients within the Polyakov-Quark-Meson model, highlighting the temperature-dependent behavior of these coefficients.

## Key findings

- Transport coefficients are in agreement with earlier results.
- Limited temperature regions are relevant due to self-energy threshold conditions.
- Thermal widths influence the strength of transport coefficients.

## Abstract

We have evaluated the transport coefficients of quark and hadronic matter in the frame work of Polyakov-Quark-Meson model. The thermal widths of quarks and mesons, which inversely control the strength of these transport coefficients, are obtained from the imaginary part of their respective self-energies at finite temperature. Due to the threshold conditions of their self energies, some limited temperature regions of quark and hadronic phase become relevant for our numerical predictions on transport coefficients, which are grossly in agreement with earlier results.
