Improvement of bottom-quark associated Higgs-boson production predictions for LHC using HERA data — •Gizhko Andrii and Geiser Achim — Deutsches Elektronen-Synchrotron, Hamburg

The dependence of the inclusive total cross section of the bottom-quark associated Higgs-boson production predictions at the LHC, pp → (bb)H+X on the treatment of the beauty quark mass is studied in the context of CMS measurements. For two different schemes (four flavour scheme (4FS) and five flavour scheme (5FS)) the theoretical uncertainty due to the beauty quark mass is estimated, and the potential improvement arising from a QCD analysis of HERA beauty data is demonstrated.
