$\rho$ meson broadening and dilepton production in heavy ion collisions

Nuclear Theory 2015-06-26 v3

Abstract

The modification of the width of the rho meson due to in-medium decays and collisions is evaluated. In high temperature and/or high density hadronic matter, the collision width is much larger than the one-loop decay width. The large width of the ρ\rho meson in matter seems to be consistent with some current interpretations of the e+ee^+ e^- mass spectra measured at the CERN/SPS.
