The cross-section for inclusive Φ meson production in pp collisions at a centre-of-mass energy of s=7 TeV has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section is measured as a function of the Φ transverse momentum pT and rapidity y in the region 0.6Search for the rare decays Bs 0 → μ+μ- and B0 → μ+μ-

A search for the decays Bs0 → μ+μ- and B0 → μ+μ- is performed with about 37 pb-1 of pp collisions at s√=7 TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branching ratios are B(Bs0 → μ+μ-)<5.6×10-8 and B(B0 → μ+μ-)<1.5×10-8 at 95% confidence level. © 2011 CERN.Determination of fs/fd for 7 TeV pp Collisions and Measurement of the B0 → D-K+ Branching Fraction
