Omega-Phi mixing at finite temperature
Charles Gale, David Seibert, Joseph Kapusta
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 b1 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.
