Аннотация
We compute the total cross-section for Higgs boson production in bottom-quark fusion using the socalled FONLL method for the matching of a scheme in which the b-quark is treated as a massless parton to that in which it is treated as a massive final-state particle, and extend our previous results to the case in which the next-to-next-to-leading-log five-flavour scheme result is combined with the next-toleading-order O( 3 s ) four-flavour scheme computation.
