3D Jet Tomography of the Twisted Color Glass Condensate

Abstract

Jet Tomography is proposed as a new test of Color Glass Condensate (CGC) initial conditions in non-central A+A collisions. The kT factorized CGC formalism is used to calculate the rapidity twist in the reaction plane of both the bulk low pT< 2 GeV matter as well as the rare high pT> 6 GeV partons. Unlike conventional perturbative QCD, the initial high pT CGC gluons are shown to be twisted even further away from the beam axis than the the low pT bulk at high rapidities |η|>2. Differential directed flow v1(pT>6,|η|>2) is proposed to test this novel high pT rapidity twist predicted by the CGC model.
