The ATLAS and CMS Detectors and Triggers for B physics

The ATLAS and CMS detectors are the two general purpose experiments which will be operated at the LHC, and these have been designed to explore the full range of physics that can be accessed at LHC energies. With the large b production cross section and high luminosity foreseen, a substantial number of b-flavoured hadrons can be expected to be recorded. For both experiments, a brief description of the most relevant detectors, the trigger systems and the trigger strategy envisaged for B physics is presented.
