3D Jet Tomography of the Twisted Color Glass Condensate

Jet Tomography is proposed as a new test of Color Glass Condensate (CGC) initial conditions in non-central $A+A$ collisions. The $k_{T}$ factorized CGC formalism is used to calculate the rapidity twist in the reaction plane of both the bulk low $p_T< 2$ GeV matter as well as the rare high $p_T> 6$ GeV partons. Unlike conventional perturbative QCD, the initial high $p_{T}$ CGC gluons are shown to be twisted even further away from the beam axis than the the low $p_T$ bulk at high rapidities $|\eta|>2$. Differential directed flow $v_{1}(p_{T}>6,|\eta|>2)$ is proposed to test this novel high $p_T$ rapidity twist predicted by the CGC model.
