Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 703:3 (2011) 267-273
Abstract:
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 0.6News from the flavour frontier - Heavy quark physics at the LHC

Abstract:
Results are presented on heavy flavour results from LHC data collected in 2010 and the early months of the 2011 run. All experiments have contributed to studies of heavy flavour production, where a wide range of measurements are now available. In the domain of heavy flavour decays there exist many observables which are highly sensitive to physics beyond the Standard Model. Here several benchmark analyses of LHCb already match or surpass in precision those of the B-factories and Tevatron. The other experiments, in particular CMS with its search for the rare decay B0s → μ+ μ-, are now augmenting this programme.Search for the rare decays Bs 0 → μ+μ- and B0 → μ+μ-

Abstract:
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.D0-(D)over-bar0 mixing studies with the decays D0 → KS0K∓π±
