Higgs production in association with bottom quarks

Articolo
Data di Pubblicazione:

Abstract:
We study the production of a Higgs boson in association with bottom quarks in hadronic collisions, and present phenomenological predictions relevant to the 13TeV LHC. Our results are accurate to the next-to-leading order in QCD, and matched to par- ton showers through the MC@NLO method; thus, they are fully differential and based on unweighted events, which we shower by using both Herwig++ and Pythia8. We perform the computation in both the four-flavour and the five-flavour schemes, whose re- sults we compare extensively at the level of exclusive observables. In the case of the Higgs transverse momentum, we also consider the analytically-resummed cross section up to the NNLO+NNLL accuracy. In addition, we analyse at O(αS3 ) the effects of the interference between the b ̄bH and gluon-fusion production modes.
