Query: Electric Conductivity of a hot hadron gas from a kinetic approach   We calculate the electric conductivity of a gas of relativistic particles
with isotropic cross sections using the Boltzmann equation as the starting
point. Our analyses is restricted to elastic collisions. We show the perfect
agreement with previously published numerical results for a massless quark-
gluon plasma, and give results for the electric conductivity of an interacting
hadron gas, employing realistic resonance cross sections. These results for the
electric conductivity of a hot hadron gas, as created in (ultra-)relativistic
heavy-ion collisions, are of rich phenomenological as well as theoretical
interest and can be compared to, e.g., lattice quantum field theory
calculations.
