Abstract
We compute the mass shifts and mixing of the Omega and Phi mesons at finite temperature due to scattering from thermal pions. The Rho and b_1 mesons are important intermediate states. Up to a temperature of 140 MeV the Omega mass increases by 12 MeV and the Phi mass decreases by 0.6 MeV. The change in mixing angles is negligible.
