Performance of the LHCb RICH detector at the LHC

M. Adinolfi, G. Aglieri Rinella, E. Albrecht +94

The LHCb experiment has been taking data at the Large Hadron Collider (LHC) at CERN since the end of 2009. One of its key detector components is the Ring-Imaging Cherenkov (RICH) s…

First observation of the decay $B^{+} \to π^{+} μ^{+} μ^{-}$

LHCb Collaboration, R. Aaij, C. Abellan Beteta +621

A discovery of the rare decay $B^{+} \to π^{+} μ^{+} μ^{-}$ is presented. This decay is observed for the first time, with 5.2 $σ$ significance. The observation is made usin…

Measurement of prompt hadron production ratios in $pp$ collisions at $s =$ 0.9 and 7 TeV

LHCb collaboration, R. Aaij, C. Abellan Beteta +619

The charged-particle production ratios $p ˉ / p$ , $K^{-} / K^{+}$ , $π^{-} / π^{+}$ , $(p + p ˉ) / (π^{+} + π^{-})$ , $(K^{+} + K^{-}) / (π^{+} + π^{-})$ and $(p + p ˉ) / (K^{+} + K^{-})$ are measured with t…

Strong constraints on the rare decays Bs -> mu+ mu- and B0 -> mu+ mu-

LHCb collaboration, R. Aaij, C. Abellan Beteta +607

A search for Bs -> mu+ mu- and B0 -> mu+ mu- decays is performed using 1.0 fb^-1 of pp collision data collected at \sqrt{s}=7 TeV with the LHCb experiment at the Large Hadron Colli…

Opposite-side flavour tagging of B mesons at the LHCb experiment

LHCb Collaboration, R. Aaij, C. Abellan Beteta +594

The calibration and performance of the opposite-side flavour tagging algorithms used for the measurements of time-dependent asymmetries at the LHCb experiment are described. The al…
