LHCb is the experiment at the Large Hadron Collider devoted to studies of new phenomena in CP violation and in rare decays. This review summarizes the status of the experiment in the imminence of the data taking, the prospects for the first measurements and highlights of its full physics program.

Rare decays of heavy-flavoured particles provide an ideal laboratory to look for deviations from the Standard Model, and explore energy regimes beyond the LHC reach. Decays proceeding via electroweak penguin diagrams are excellent probes to search fo
r New Physics, and $b to s ell^{+}ell^{-}$ processes are particularly interesting since they give access to many observables such as branching fractions, asymmetries and angular observables. Recent results from the LHCb experiment are reviewed.
We report on the first searches for lepton flavour violating $tau^-$ decays at a hadron collider. These include searches for the lepton flavour violating decay $tau^-to mu^+mu^-mu^-$ and the lepton flavour and baryon number violating decays $tau^-to
bar{p}mu^+mu^-$ and $tau^-to pmu^-mu^-$. Upper limits of ${cal B}(tau^-to mu^+mu^-mu^-) < 4.6 times 10^{-8}$, ${cal B}(tau^-to bar{p}mu^+mu^-) < 3.4 times 10^{-7}$ and ${cal B}(tau^-to pmu^-mu^-) < 4.6 times 10^{-7}$ are set at 90% confidence level. A measurement of the inclusive $Ztotau^+tau^-$ cross-section at 7 TeV is also reported and is found to be consistent with the Standard Model. The ratio of the $Ztotau^+tau^-$ cross-section to the $Ztomu^+mu^-$ cross-section is found to be consistent with lepton universality.
Data collected by the LHCb experiment allow proton structure functions to be probed in a kinematic region beyond the reach of other experiments, both at the LHC and further afield. In these proceedings the significant impact of LHCb Run 1 measurement
s on PDF fits is recalled and recent LHCb results, that are sensitive to PDFs, are described.
Despite not being designed for it, the LHCb experiment has given world-leading contributions in kaon and hyperon physics. In this contribution I review the prospects for kaon physics at LHCb exploiting the already acquired data and the current and future Upgrade scenarios.
We report on the first measurements of the LHCb experiment, as obtained from $pp$ collisions at $sqrt{s} = 0.9$ TeV and 7 TeV recorded using a minimum bias trigger. In particular measurements of the absolute $K^0_S$ production cross section at $sqrt{
s} = 0.9$ TeV and of the $bar{Lambda}/Lambda$ ratio both at $sqrt{s} = 0.9$ TeV and 7 TeV are discussed and preliminary results are presented.
