Description
The dispersion relation of the pion quasiparticle is calculated in the
confined phase of QCD with two light flavors of quarks using lattice
simulations. In the hadron gas, the would-be diffusion pole of the
axial charge density and the Goldstone boson of chiral symmetry
breaking "mix"; as a result, a single light quasiparticle emerges
whose dispersion relation can be determined from equilibrium
quantities (D.T. Son and M. Stephanov, Phys. Rev. D66 (2002)
076011). Results are presented for temperatures between $0.7T_c$ and $T_c$.
