Large $N_{c}$, chiral approach to $M_{\eta}'$ at finite temperature
We study the temperature dependence of the eta and eta' meson masses withinthe framework of U(3)_L x U(3)_R chiral perturbation theory, up tonext-to-leading order in a simultaneous expansion in momenta, quark masses andnumber of colours. We find that both masses decrease at low temperatures, bu...
