LHCb prospects in flavour physics and CP violation

A selection of key measurements of the LHCb physics programme is reviewed where competitive results can be expected from the first year of data taking. The LHCb experiment will search for New Physics in $B_S$ mixing, notably through the measurement of the $B_s$ mixing phase $\phi_s$ from the time-dependent CP asymmetry in exclusive $B_s$ decays governed by the $b \to c\bar{c}s$ quark-level transition. The LHCb experiment will exploit a number of methods to measure the CKM angle $\gamma$ from $B \to DK$ tree decays, with the goal of reaching a precision comparable to the indirect determinations of $\gamma$ within the CKM model. The LHCb experiment will search for New Physics in $B^0_s \to \mu^+ \mu^-$ and $B_0 \to K^* \mu^+ \mu^-$ decays, for the former decay with a 90% CL exclusion sensitivity down to the Standard Model prediction.
