Abstract
We analyze transverse momentum () resummation of a colorless final state, e.g. Higgs production in gluon fusion or the production of a lepton pair via the Drell-Yan mechanism, in the limit where the invariant mass of the final state is much less then the center-of-mass energy, i.e. . We show how the traditional resummation of logarithms of can be supplemented with the resummation of the leading logarithmic contributions at small and we compute the necessary ingredients to perform such joint resummation.
