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…
Observation of X(3872) production in pp collisions at sqrt(s)= 7 TeV
LHCb Collaboration, R. Aaij, C. Abellan Beteta +585
Using 34.7 pb-1 of data collected with the LHCb detector, the inclusive production of the X(3872) meson in pp collisions at sqrt(s) = 7 TeV is observed for the first time. Candidat…
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…
Evidence for CP violation in time-integrated D0 -> h-h+ decay rates
LHCb Collaboration, R. Aaij, C. Abellan Beteta +586
A search for time-integrated CP violation in D0 -> h-h+ (h=K, pi) decays is presented using 0.62 fb^-1 of data collected by LHCb in 2011. The flavor of the charm meson is determine…
Measurement of b hadron production fractions in 7 TeV pp collisions
The LHCb Collaboration, R. Aaij, C. Abellan Beteta +587
Measurements of hadron production ratios in proton-proton collisions at a centre-of-mass energy of 7 TeV with an integrated luminosity of 3 pb are presented. We study th…
