Enhancement of low-mass dileptons in heavy-ion collisions
G. Q. Li, C. M. Ko, G. E. Brown
Abstract
Using a relativistic transport model for the expansion stage of S+Au collisions at 200 GeV/nucleon, we show that the recently observed enhancement of low-mass dileptons by the CERES collaboration can be explained by the decrease of vector meson masses in hot and dense hadronic matter.
