[en] The vector and axial vector current mixing phenomena at low temperature pion gas by Dey, Eletsky and Ioffe, leads to the low temperature correction of the photon-vector meson coupling (gp) at order ε=T2/6fπ2 and the ρ meson mass at order ε2. In this talk, I first show how this low temperature theorems are satisfied in QCD sum rules and effective chiral models and then discuss other temperature effects involving the vector mesons within these models.
