Minijet-associated dilepton production in ultrarelativistic heavy ion collisions.
نویسندگان
چکیده
Dilepton production associated with minijets is calculated in ultrarela-tivistic 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 AGeV for small dilepton invariant mass M ∼ 1-2 GeV/c 2 while dominant over a large range of mass at √ s = 6400 AGeV.

Elliptic Flow from Minijet Production in Heavy Ion Collisions
We calculate the contribution to the elliptic flow observable v2 from two–particle correlations in minijet production in ultrarelativistic heavy ion collisions. We use a minijet production cross section derived in a model inspired by saturation approach to high energy scattering. Resulting differential elliptic flow v2(pT ) is an increasing function of pT for transverse momenta below the satura...

متن کاملMINIJETS IN ULTRARELATIVISTIC HEAVY ION COLLISIONS AT RHIC AND LHC K.J.Eskola
Recent results on minijet production in nuclear collisions at the RHIC and LHC energies are reviewed. Initial conditions of the QGP at τ = 0.1 fm/c, especially parton chemistry, thermalization and net baryon number-to-entropy ratio are discussed. Also, contribution of minijets from a hard BFKL-pomeron ladder will be estimated.
متن کاملMinijet and Transverse Energy Production in the BFKL Regime
Minijet production in hadronic and nuclear collisions through a BFKL pomeron ladder is studied for the energies of the future LHC heavy-ion collisions. We use unintegrated gluon densities compatible with the small-x increase of parton distributions observed at HERA. We show that at LHC energies the BFKL minijet and transverse energy production is at most of the same order of magnitude as that i...

Secondary phi meson peak as an indicator of QCD phase transition in ultrarelativistic heavy ion collisions Abstract In a previous paper, we have shown that a double phi peak structure appears in the dilepton invariant mass spectrum if a first order QCD phase transition occurs in ultrarelativistic heavy ion collisions. Furthermore, the transition temperature can be determined from the transverse...
