LHCb is a dedicated detector for b physics at the LHC. In this article we present a concise review of the detector design and performance together with the main physics goals and their relevance for a precise test of the Standard Model and search of New Physics beyond it.

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.
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.

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.

This article is a short and non-exhaustive summary of the prospects to find New Physics with LHCb as was presented at the HCP conference at Toronto on August 26th 2010.
It is interesting to search for new physics beyond the standard model at LHCb. We suggest that weak decays of doubly charmed baryon such as $Xi_{cc}(3520)^+, Xi_{cc}^{++}$ to charmless final states would be a possible signal for new physics. In this work, we consider two models, i.e. the unparticle and $Z$ as examples to study such possibilities. We also discuss the cases for $Xi^0_{bb}, Xi_{bb}^-$ which have not been observed yet, but one can expect to find them when LHCb begins running. Our numerical results show that these two models cannot result in sufficiently large decay widths, therefore if such modes are observed at LHCb, there must be a new physics other than the unparticle or $Z$ models.
