Abstract

The transverse momentum () distribution of Higgs bosons at hadron colliders enables a detailed probe of its production dynamics and is a key ingredient to precision studies of Higgs boson properties, but receives very large QCD corrections. We obtain a precision prediction for the spectrum by matching second-order (NNLO) QCD corrections at large with resummation of third-order logarithmic (N3LL) corrections at small . We achieve significantly improved results for with perturbative uncertainties , and thus a convergent perturbative series for all values of pT.
