Abstract
The decay of the omega meson in a heat bath of thermally excited pions is s tudied within the framework of real-time thermal field theory using an appr opriate effective Lagrangian. We show that the omega meson spectrum broaden s considerably at temperatures T > 100 MeV, primarily because of omega pi - -> pi pi reactions in the thermal environment. @ 2001 Published by Elsevier Science B.V.
