ATLAS and CMS

The ATLAS [11] and CMS [12] detectors at the LHC are optimised for high luminosity physics. But initial low luminosity running will allow these general purpose detectors to used for B physics. Both detectors are installing silicon vertex detectors close to the beampipe. More detailed discussion of these detectors and their physics performance can be found elsewhere in these proceedings [13].
