TL;DR
The single-inclusive minijet cross section in pA at forward rapidity within the color glass condensate model of high energy collisions is considered and it is shown that the nucleus appears black to the incident quarks except for very large impact parameters.
Abstract
We consider the single-inclusive minijet cross section in pA at forward rapidity within the Color Glass Condensate model of high energy collisions. We show that the nucleus appears black to the incident quarks except for very large impact parameters. A markedly flatter p_t distribution as compared to QCD in the dilute perturbative limit is predicted for transverse momenta about the saturation scale, which could be as large as Q_s^2 ~ 10 GeV^2 for a gold nucleus boosted to rapidity ~10 (as at the BNL-RHIC).
