Precise QCD Description of the Higgs Boson Transverse Momentum Spectrum
The transverse momentum ( pT ) 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 pT spectrum by...

| description | The transverse momentum ( pT ) 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 pT spectrum by matching second-order (NNLO) QCD corrections at large pT with resummation of third-order logarithmic (N 3 LL) corrections at small pT . We achieve significantly improved results for pT<35 GeV with perturbative uncertainties ≲±6% , and thus a convergent perturbative series for all values of pT . |

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 (N$^3$LL) corrections at small $p_T$. We achieve significantly improved results for $p_T< 35\,{\rm GeV}$ with perturbative uncertainties $\lesssim \pm 6\%$, and thus a convergent perturbative series for all values of $p_T$.arXiv:1805.00736IPPP/18/28ZU-TH 16/18CERN-TH-2018-108MIT-CTP 5013HU-EP-18/14FERMILAB-PUB-18-212-Toai:cds.cern.ch:23187832018-05-02 |
