At the LHC, B-hadrons will be produced in a very high quantity at an 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 will be
discussed on the basis of realistic detector simulations. Systematic
effects which are limiting the accessible range of differential cross
sections will be 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 will be addressed, including triggers, offline
techniques and a discussion of the expected performance in terms of
efficiencies and misidentification probabilities under realistic
conditions. Approaches to measure these efficiencies with real data will
also be presented.
