Measurement of the time-dependent CP asymmetry in B0 → J/ψ K0S decays
(Elsevier, 2013-04-10)
This Letter reports a measurement of the CP violation observables S J/ψK0S and C J/ψK0S in the decay channel B0 → J/ψ K0S performed with 1.0 fb-1 of pp collisions at √s = 7 TeV collected by the LHCb ...
Measurement of the D+s − D−s production asymmetry in 7 TeV pp collisions
(Elsevier, 2012-07-09)
Heavy quark production in 7 TeV centre-of-mass energy pp collisions at the LHC is not necessarily flavour symmetric. The production asymmetry, A_P, between Ds+ and Ds- mesons is studied using the ...
Prompt Kshort production in pp collisions at sqrt(s)=0.9 TeV
(Elsevier, 2010-09-27)
The production of K_short mesons in pp collisions at a centre-of-mass energy of 0.9 TeV is studied with the LHCb detector at the Large Hadron Collider. The luminosity of the analysed sample is determined ...
Measurement of the D± production asymmetry in 7 TeV pp collisions
(Elsevier, 2013-01-08)
The asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T ...
Measurement of the effective B0s → K+K- lifetime
(Elsevier, 2012-10-02)
A precise determination of the effectiveB0s→K+K−lifetime can be used to con-strain contributions from physics beyond the Standard Model in theB0smesonsystem. Conventional approaches selectBmeson ...
First observation of the decay B¯0s→D0K∗0 and a measurement of the ratio of branching fractions B(B¯0s→D0K∗0)/B(B¯0→D0ρ0)
(Elsevier, 2011-11-30)
The first observation of the decay B¯s0→D0K⁎0 using pp data collected by the LHCb detector at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 36 pb−1 , is reported. A ...
Measurement of the polarization amplitudes and triple product asymmetries in the B s 0 → ϕ ϕ decay

Measurement of the CKM angle γ from a combination of B±→Dh± analyses
(Elsevier, 2013-10-07)
A combination of three LHCb measurements of the CKM angle gamma is presented. The decays B-+/- -> DK +/- and B-+/- -> D pi(+/-) are used, where D denotes an admixture of D-0 and (D) over bar (0) mesons, ...
