Abstract

We extend the previously developed small x parton shower algorithm to include the kinematic constraint effect and k_t resummation effect. This work enables the Monte Carlo generator to simultaneously resum large k_t and small x logarithms in the saturation regime for the first time. It is an important step towards simulating processes involving multiple well separated hard scales, such as di-jet production in eA collisions at EIC.
