Differential branching fraction and angular analysis of the decay B0sϕμ+μ / LHCb Collaboration
The determination of the differential branching fraction and the first angular analysis of the decay B0sϕμ+μ are presented using data, corresponding to an integrated luminosity of 1.0fb1, collected by the LHCb experiment at s=7TeV. The differential branching fraction is determined in bins of q2, the invariant dimuon mass squared. [...]

First observation of CP violation in the decays of B0s mesons / LHCb Collaboration
Using pp collision data corresponding to an integrated luminosity of 1.0fb1 and collected by LHCb in 2011 at a center-of-mass energy of 7 TeV, we report the measurement of direct CP violation in B0sKπ+ decays, ACP(B0sKπ+)=0.27±0.04(stat)±0.01(syst), with significance exceeding 5 standard deviations. This is the first observation of CP violation in the decays of B0s mesons. [...]

Searches for violation of lepton flavour and baryon number in tau lepton decays at LHCb / LHCb Collaboration
Searches for the lepton flavour violating decay τμμ+μ and the lepton flavour and baryon number violating decays τˉpμ+μ and τpμμ have been carried out using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb1, taken by the LHCb experiment at s=7 TeV. No evidence has been found for any signal, and limits have been set at 90% confidence level on the branching fractions: B(τμμ+μ)<8.0×108, B(τˉpμ+μ)<3.3×107 and B(τpμμ)<4.4×107. [...]

A study of D+K0S and D0K+ final states is performed in a sample of 1.0 fb1 of pp collision data collected at a centre-of-mass energy of s=7 TeV with the LHCb detector.
