Beauty Production and Identification at CMS

Abstract

At the LHC, b-hadrons will be produced in a very high quantity at a yet unreached center-of-mass energy, enabling precision measurements to improve our understanding of the physics of b-quarks. The capability to measure the inclusive b-hadron production cross section is discussed on the basis of realistic detector simulations. Effects which are limiting the accessible range of differential cross sections are outlined. The identification of b-jets is a crucial tool for a large number of topics, like top quark physics, and potential discoveries of the Higgs Boson and Supersymmetry. The applied methods of identifying b-jets are addressed and a discussion of the expected performance in terms of efficiencies and misidentification probabilities under realistic conditions is given. Approaches to measure these efficiencies with real data are also presented.
