Measurement of J/psi production in pp collisions at sqrt(s)=2.76 TeV
LHCb collaboration, R. Aaij, C. Abellan Beteta +624
The production of J/psi mesons is studied with the LHCb detector using data from pp collisions at sqrt(s)=2.76 TeV corresponding to an integrated luminosity of 71 nb^-1. The differ…
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…
Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
LHCb collaboration, R. Aaij, C. Abellan Beteta +622
This Letter reports a measurement of the CP violation observables S_J/ψKS0 and C_J/ψKS0 in the decay channel B0 -> J/ψ KS0 performed with 1.0/fb of pp collisions at sqrt(s) = 7 TeV…
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…
Observation of D0-D0bar oscillations
LHCb collaboration, R. Aaij, C. Abellan Beteta +616
We report a measurement of the time-dependent ratio of D0->K+pi- to D0->K-pi+ decay rates in D*+-tagged events using 1.0 fb^{-1} of integrated luminosity recorded by the LHCb exper…
