Dilepton from Passage of Jets Through Spherical Expanding QGP

We calculate the large mass dileptons production from the jet-dilepton conversion in spherical expanding quark-gluon plasma at Relativistic Heavy Ion Collider(RHIC) and Large Hadron Collider(LHC) energies.The jetdilepton production exceeds the thermal and Drell Yan dilepton production in the large mass region of 4.5 GeVM 5.5 GeV and 7 GeV M 9 GeV in central Pb+Pb collisions at SNNS~(1/2)=2.76 TeV and 5.5 TeV,respectively.We present the solution of(1+3)-dimensional fluid hydrodynamics with spherical symmetry.We find that the transverse flow of the QGP leads to a rapid cooling of the fire ball and suppression of the jet-dilepton conversion.The suppression is also evident at intermediate and large mass at LHC energies.The energy loss of the jet-dilepton conversion is concerned.
