Description
Hadron identification, in particular the ability to distinguish
charged kaons and pions, is crucial to many of LHCb core physics
analyses. LHCb Ring Imaging Cherenkov (RICH) detector fulfills this
role by providing charged particle identification in the momentum
range between 1 and 100 GeV/c. The calibration and monitoring of the
RICH detectors is achieved using samples of $D^{*}$, $K_{S}^{0}$, $
\Lambda$ and $\phi$ events, which are plentiful in the data and can be
cleanly isolated through their decay kinematics. The particle
identification performance of the LHCb RICH detectors, measured in
data taken during the 2010 and 2011 LHC runs, will be presented along
with the strategy for aligning and calibrating the detector. Finally
this performance will be placed in context by highlighting the impact
of the RICH performance on some of LHCb benchmark analyses.
