Initial momentum anisotropies in the kT-factorization of the CGC I: Gradient Expansion
Oscar Garcia-Montero
We revisit single-inclusive gluon production in the dilute--dilute limit of the Color Glass Condensate and show that -factorization is only the zeroth order of a systemati…
Fundamental geometric limitations on disentangling nuclear-surface properties in relativistic heavy ion collisions
