Jet-dilepton conversion from an anisotropic quark-gluon plasma

TL;DR

This paper calculates lepton pair production from jet-plasma interactions in an anisotropic quark-gluon plasma, showing it dominates over Drell-Yan processes at certain energies and is slightly enhanced compared to isotropic plasma.

Contribution

It introduces the calculation of lepton pair yields from jet-plasma interactions specifically in an anisotropic quark-gluon plasma, highlighting differences from isotropic cases.

Findings

Lepton pair yield from jet-plasma interactions dominates Drell-Yan up to 3 GeV at RHIC and 10 GeV at LHC.

Anisotropic QGP marginally increases the lepton yield compared to isotropic QGP.

At RHIC, the p_T distribution increases by a factor of 3-4 in the entire range for AQGP.

Abstract

We calculate the yield of lepton pair production from jet-plasma interaction where the plasma is anisotropic in momentum space. We compare both the $M$ and $p_T$ distributions from such process with the Drell-Yan contribution. It is observed that the invariant mass distribution of lepton pair from such process dominate over the Drell-Yan up to $3$ GeV at RHIC and up to $10$ GeV at LHC. Moreover, it is found that the contribution from anistropic quark gluon plasma (AQGP) increases marginally compared to the isotropic QGP. In case of $p_T$-distribution we observe an increase by a factor of $3-4$ in the entire $p_T$-range at RHIC for AQGP. However, at LHC the change in the $p_T$-distribution is marginal as compared to the isotropic case.
