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…
Search for CP violation in decays
LHCb Collaboration, R. Aaij, B. Adeva +573
A model-independent search for direct CP violation in the Cabibbo suppressed decay in a sample of approximately 370,000 decays is carried out. The data were co…

LHCb Collaboration, R. Aaij, B. Adeva +567
The production of pairs in proton-proton collisions at a centre-of-mass energy of 7 TeV has been observed using an integrated luminosity of collected with the…
Measurement of the inclusive phi cross-section in pp collisions at sqrt(s) = 7 TeV
LHCb Collaboration, R. Aaij, B. Adeva +551
The cross-section for inclusive phi meson production in pp collisions at a centre-of-mass energy of sqrt(s) = 7 TeV has been measured with the LHCb detector at the Large Hadron Col…
Estimates for solutions of the -equation and application to the characterization of the zero varieties of the functions of the nevanlinna class for lineally convex domains of finite type
Philippe Charpentier, Yves Dupain, Modi Mounkaila
In the late ten years, the resolution of the equation with sharp estimates has been intensively studied for convex domains of finite type by many authors. In thi…
