Suppression of dilepton production in hot hadronic matter
Dilepton production from pion-pion annihilation in a hot hadronic matter is studied using an effective chiral Lagrangian that includes explicitly vector mesons. We find that the production rate for dileptons with invariant masses around the \ensuremath{\rho}-meson resonance is suppressed as a result of the modification of the pion electromagnetic form …
