The LHCb Trigger and its Performance in 2011
R. Aaij, J. Albrecht, F. Alessio +80
This paper presents the design of the LHCb trigger and its performance on data taken at the LHC in 2011. A principal goal of LHCb is to perform flavour physics measurements, and th…
Evidence for the decay and measurement of the relative branching fractions of meson decays to and
LHCb Collaboration, R. Aaij, C. Abellan Beteta +620
First evidence of the decay is found and the and decays are studied using a dataset corresponding to an integrated lumino…
Measurements of production and mass with the decay
LHCb collaboration, R. Aaij, C. Abellan Beteta +617
Measurements of production and mass are performed with the decay mode using 0.37 fb of data collected in collisions at TeV by th…
Measurement of the effective lifetime
LHCb collaboration, R. Aaij, C. Abellan Beteta +616
A precise determination of the effective lifetime can be used to constrain contributions from physics beyond the Standard Model in the meson sys…
Measurement of the Ds+ - Ds- production asymmetry in 7 TeV pp collisions
LHCb collaboration, R. Aaij, C. Abellan Beteta +605
Heavy quark production in 7 TeV centre-of-mass energy pp collisions at the LHC is not necessarily flavour symmetric. The production asymmetry, A_P, between Ds+ and Ds- mesons is st…
Measurement of -hadron branching fractions for two-body decays into charmless charged hadrons
LHCb collaboration, R. Aaij, C. Abellan Beteta +589
Based on data corresponding to an integrated luminosity of 0.37 fb^-1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: B(B0 -> pi…
