First evidence for the decay Bs -> mu+ mu-
LHCb collaboration, R. Aaij, C. Abellan Beteta +617
A search for the rare decays Bs->mu+mu- and B0->mu+mu- is performed using data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples co…
First observation of the decay and studies of excited mesons
LHCb collaboration, R. Aaij, C. Abellan Beteta +621
Properties of the orbitally excited (L=1) states are studied using 1.0 fb of pp collisions at TeV collected with the LHCb detector. The first observation…
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…
First observation of the decay
LHCb Collaboration, R. Aaij, C. Abellan Beteta +621
A discovery of the rare decay is presented. This decay is observed for the first time, with 5.2 significance. The observation is made usin…
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…
Inclusive and production in the forward region at TeV
LHCb collaboration, R. Aaij, C. Abellan Beteta +606
Measurements of inclusive and boson production cross-sections in collisions at TeV using final states containing muons are presented. The data sample corr…
Measurement of psi(2S) meson production in pp collisions at sqrt(s)=7 TeV
LHCb collaboration, R. Aaij, C. Abellán Beteta +577
The differential cross-section for the inclusive production of psi(2S) mesons in pp collisions at sqrt(s)=7 TeV has been measured with the LHCb detector. The data sample correspond…
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…
Measurement of the B+- production cross-section in pp collisions at sqrt(s)=7 TeV
The LHCb Collaboration, R. Aaij, C. Abellan Beteta +594
The production of B+- mesons in proton-proton collisions at sqrt(s)=7 TeV is studied using 35 pb-1 of data collected by the LHCb detector. The B+- mesons are reconstructed exclusiv…
First evidence of direct CP violation in charmless two-body decays of Bs mesons
LHCb collaboration, R. Aaij, C. Abellan Beteta +591
Using a data sample corresponding to an integrated luminosity of 0.35 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of $B…
Determination of the sign of the decay width difference in the B_s system
LHCb Collaboration, R. Aaij, C. Abellan Beteta +594
The interference between the K+K- S-wave and P-wave amplitudes in B_s -> J/psi K+K- decays with the K+K- pairs in the region around the phi(1020) resonance is used to determine the…
