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…

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…
