Temperature Dependence of \eta and \eta^{\prime} Masses

Abstract

We investigate the temperature dependence of \eta and \eta^{\prime} masses due to scatterings from thermal pions in a heat bath using the non-linear sigma model. We show that mass shifts of \eta and \eta^{\prime} and the shift in the mixing angle are negligible.
