Collective interaction of mesons in hot hadronic matter

Abstract

We calculate the momentum-dependent optical potentials (both real and imaginary parts) for mesons propagation in hadronic matter at T= 100–170 MeV. The observable consequences are modifications of the spectra of the outgoing pions, producing a peak at small p t , as well as significant increase in the width of φ, ω mesons, decaying inside the matter.
