摘要: Abstract We discuss the modification of dipleton yield from vector mesons inside a nuclear fireball. argue that relative magnitude ϱ peak in dilepton spectrum determines lifetime hadron gas phase collisions with an accuracy about 1 fm/ c . also find φ (ω + ϱ) ratio measured dimuon channel 200 A GeV O U and S points towards rather short-lived hadronic these collisions.
