Combined threshold and transverse momentum resummation for inclusive observables

by Giovanni Ridolfi

OC218 (IPPP)



I present a combined resummation for the transverse momentum distribution of a colorless final state in perturbative QCD. Our result satisfies three requirements: it reduces to standard transverse momentum resummation to any desired logarithmic order in the small-p_T for fixed radiation energy; it reduces to threshold resummation to any desired logarithmic order in the threshold limit for fixed p_T; upon transverse momentum integration it reproduces the threshold resummation of the total cross section. I present some preliminary results and comparisons with standard resummation in the specific case of Higgs production in gluon fusion in the effective field theory limit.
