Abstract

Dilepton production associated with minijets is calculated in ultrarelativistic heavy ion collisions using the first order approximation of the dilepton fragmentation functions of quarks and gluons. The full QCD evolution of the fragmentation functions is also studied. We find that the dilepton pairs from the fragmentation of minijets are comparable to direct Drell-Yan at s=200\sqrt{s}=200 AGeV for small dilepton invariant mass MM\sim 1-2 GeV/c2^2 while dominant over a large range of mass at s=6400\sqrt{s}=6400 AGeV.
