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 (gρ{variant}) at order ε{lunate} = T2/6f{hook}π 2 and the ρ{variant} meson mass at order ε{lunate}2. We show how the low temperature theorems involving the photon and vector mesons are satisfied in the chiral models based on hidden gauge symmetry and the massive Yang-Mills approach with an explicit a1 meson. We discuss possible phenomenological consequences of the low temperature corrections in RHIC experiments.
