Precise QCD description of the Higgs boson transverse momentum spectrum

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 ((NLL)-L-3) corrections at small P-T. We achieve significantly improved results for p(T) < 35 GeV with perturbative uncertainties less than or similar to +/- 6%, and thus a convergent perturbative series for all values of P-T.
