Description
Precise theoretical predictions of physical processes at hadron colliders are a fundamental ingredient of the LHC precision programme. In the production of a heavy quark pair in proton-proton collisions, the final-state invariant mass can be much smaller than the collider energy. Under these conditions, high-energy logarithms may spoil the perturbativity of fixed order perturbation theory. Thus, the resummation of these logarithms to all orders is needed to obtain reliable predictions. In this talk, I'll illustrate an extension of the high-energy (or small-$x$) resummation formalism for differential distributions in rapidity and transverse momentum as well as its implementation in the public code HELL for charm and bottom pair production.
