LHCb: detector performance and first physics results

Key words LHCb, b physics, CP violation, rare b decays. LHCb is a dedicated detector for b and c physics at the LHC. I will present a concise review of the detector design and performance together with a selection of early physics results and prospects. The integrated lu-minosity of 37 pb−1 collected in 2010 has already allowed LHCb to perform a number of a very significant measurements, while the data expected for 2011 have the potential of revealing New Physics effects in the Bs sector.
