Description

We consider the transverse momentum (q_T) distribution of Higgs bosons produced at hadron colliders. At small q_T the logarithmically enhanced contributions are resummed to all orders up to next-to-next-to-leading logarithmic accuracy. The result is consistently matched to the fixed order perturbative expansion at next-to-leading order, valid at large q_T. The introduction of unjustified higher-order terms in the intermediate region is avoided by imposing unitarity constraints, such that the total cross section at next-to-next-to leading order is recovered upon integration. Numerical results at the LHC are presented.
