Higgs boson production with one bottom quark jet at hadron colliders

TL;DR

Total rates and kinematic distributions for the associated production of a single bottom quark and a Higgs boson at the Fermilab Tevatron and CERN Large Hardon Collider are presented.

Abstract

We present total rates and kinematic distributions for the associated production of a single bottom quark and a Higgs boson at the Tevatron and the LHC. We include next-to-leading order QCD corrections and compare the results obtained in the four and five flavor number schemes for parton distribution functions.

• Figure 2: Feynman diagrams for $gb\rightarrow bh$ production at tree level.
• Figure 3: Feynman diagram for the closed top quark loop contribution to $gb\rightarrow bh$.
• Figure 4: Total LO and NLO cross sections for $pp,p\bar{p}\to b(\bar{b}) h$ production in the 4FNS as a function of $\mu\!=\!\mu_r\!=\!\mu_f$ for $M_h\!=\!120$ GeV, at both the Tevatron and the LHC.
• Figure 5: Total NLO cross section for $pp,p\bar{p}\to b(\bar{b}) h$ production at the Tevatron and the LHC as a function of $M_h$. We have assumed $\mu_r\!=\!\mu_f\!=\!\mu_0/2$ for the central curves (see inlays) and varied $\mu_r$ and $\mu_f$ independently to obtain the uncertainty bands, as explained in the text. The solid curves correspond to the 4FNS, the dashed curves to the 5FNS.
