dc.description.abstract
We study the production of a Higgs boson in association with bottom quarks (bb¯¯H) in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa coupling (y t 2 ), to the bottom-quark one (y b 2 ), and to their interference (ybyt). Our results are accurate to next-to-leading order in QCD, employ the four-flavour scheme and the (Born-improved) heavy-top quark approximation. We find that next-to-leading order corrections to the y t 2 component are sizable, making it the dominant production mechanism for associated bb¯¯H production in the Standard Model and increasing its inclusive rate by almost a factor of two. By studying final-state distributions of the various contributions, we identify observables and selection cuts that can be used to select the various components and to improve the experimental sensitivity of bb¯¯H production on the bottom-quark Yukawa coupling.
