Bulk viscosity of a gas of massless pions
In the hadronic phase, the dominant configuration of quantum chromodynamics (QCD) with two flavors of massless quarks is a gas of massless pions. We calculate the bulk viscosity (ζ) using the Boltzmann equation with the kinetic theory generalized to incorporate the trace anomaly. We find that the di...
