Measurement of mixing and CP violation parameters in two-body charm decays
LHCb Collaboration, R. Aaij, C. Abellan Beteta +585
A study of mixing and indirect CP violation in D0 mesons through the determination of the parameters y_CP and A_Γ is presented. The parameter y_CP is the deviation from unity of th…
Measurement of charged particle multiplicities in collisions at TeV in the forward region
LHCb Collaboration, R. Aaij, C. Abellan Beteta +589
The charged particle production in proton-proton collisions is studied with the LHCb detector at a centre-of-mass energy of TeV in different intervals of pseudorapid…
Measurement of b-hadron masses
LHCb Collaboration, R. Aaij, C. Abellan Beteta +583
Measurements of b-hadron masses are performed with the exclusive decay modes B+ -> J/psi K+, B0 -> J/psi K*0, B0 -> J/psi K0S, B0_s -> J/psi phi and Lambda_b -> J/psi Lambda using…
Observation of Bs -> J/ψf'2(1525) in J/ψK+K- final states
LHCb Collaboration, R. Aaij, C. Abellan Beteta +583
The decay Bs -> J/ψK+ K- is investigated using 0.16/fb of data collected with the LHCb detector using 7 TeV pp collisions. Although the J/ψϕ channel is well known, final states at…
Differential branching fraction and angular analysis of the decay
LHCb Collaboration, R. Aaij, C. Abellan Beteta +585
The angular distributions and the partial branching fraction of the decay are studied using an integrated luminosity of of data c…
Measurement of the CP-violating phase phi_s in the decay Bs->J/psi phi
LHCb Collaboration, R. Aaij, C. Abellan Beteta +585
We present a measurement of the time-dependent CP-violating asymmetry in B_s -> J/psi phi decays, using data collected with the LHCb detector at the LHC. The decay time distributio…
