Abstract:
We show that in a hot hadron gas, chiral symmetry restoration and deconfinement lead to a strong suppression of dilepton production by pion annihilation in the continuum above the ρωϕ\rho-\omega-\phi peak. The suppression due to deconfinement persists also for annihilation reactions involving heavier mesons.
