B decays, CKM, spectroscopy and charm at LHCb

Precise measurements of CP violation and searches for rare decays have a high potential for discovering effects of new physics. They are a specific task of the LHCb experiment and are complementary to direct searches performed by general purpose LHC experiments (ATLAS and CMS). In this review only part of the broad physics program of LHCb can be covered, additional information can be found in other contributions to this Conference [1]. LHCb is a single arm forward detector at the LHC which covers the region of pseudo-rapidity 2 < $\eta$ 5 where the production of $b\bar{b}$ and $c\bar{c}$ pairs from $pp$ collisions at $\sqrt{s}$ = 7 TeV is copious. A full description of the LHCb detector and main performance can be found in [2,3]. During the run of LHC at $\sqrt{s}$ 7 TeV in 2010 LHCb collected about 36 pb$^{-1}$ of data, while an integrated luminosity of about 1 pb$^{-1}$ is expected by the end of 2011. The preliminary results of the analysis of the 2010 data are presented in the following.
