Meson thermal masses at different temperatures
Abstract
We determine the ground state meson masses at low temperature using simulations with 2+1 flavours of improved Wilson-clover fermions. Subsequently we study the effect of increasing the temperature of the hadron gas, including the transition to the quark-gluon plasma, as well as the restoration of SU(2)A chiral symmetry. We use the FASTSUM anisotropic, fixed-scale Generation2L ensembles and consider mesons with light, strange and charm content.
