    In this Reply, we respond to the above Comment. Our computation [Phys. Rev. D 91 (2015) 074512] only took into account pure QCD effects, arising from quark mass differences, so it is not surprising that there are discrepancies in isospin splittings and in the Sigma - Lambda mixing angle. We expect that these discrepancies will be smaller in a full calculation incorporating QED effects.

    Analytic solution of the Boltzmann equation in an expanding system

    D. Bazow (Ohio State U.)🇺🇸 · G. S. Denicol (Brookhaven & McGill U.)🇨🇦 · U. Heinz (Ohio State U.)🇺🇸 · M. Martinez (Ohio State U.)🇺🇸 · J. Noronha (Sao Paulo U. & Columbia U.)🇧🇷

    For a massless gas with constant cross section in a homogeneous, isotropically expanding spacetime we reformulate the relativistic Boltzmann equation as a set of non-linear coupled moment equations. For a particular initial condition this set can be solved exactly, yielding the first analytical solution of the Boltzmann equation for an expanding system. The non-equilibrium behavior of this relativistic gas can be mapped onto that of a homogeneous, static non-relativistic gas of Maxwell molecules.
