CMS B physics reach

Abstract

At the design luminosity of 10³⁴ cm^–2 s^–1, about 10⁶ $\ensuremath{\mathrm{b}\bar{\mathrm{b}}}$ pairs are expected to be produced every second at the Large Hadron Collider. With such huge statistics and the precise tracking of the CMS detector B mesons can be investigated for CP violation, $\ensuremath{\mathrm{B^{0}_{s}\mbox{-}\bar{B}^{0}_{s}}}$ mixing and rare decays. The trigger, however, cannot retain all $\ensuremath{\mathrm{b}\bar{\mathrm{b}}}$ events for a later selection of exclusive B decays. A dedicated trigger strategy, which uses tracking immediately after the first trigger stage, is presented and results on few important benchmark channels are given.
