Abstract
The transverse momentum (p T ) 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 p T spectrum by matching second-order (NNLO) QCD corrections at large p T with resummation of third-order logarithmic (N³LL) corrections at small p[subscript T]. We achieve significantly improved results for p[subscript T] <35 GeV with perturbative uncertainties ≲±6%, and thus a convergent perturbative series for all values of p[subscript T].
