Measurement of the cross-section ratio σ(χc2)/σ(χc1) for prompt χc production at √s=7TeV
(Elsevier, 2012-08-14)
The prompt production of the charmonium $\chi_{c1}$ and $\chi_{c2}$ mesons has been studied in proton-proton collisions at the Large Hadron Collider at a centre-of-mass energy of $\sqrt{s}=7$ TeV. 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 CP-violating phase φs in B0s→J/ψπ+π− decays
(Elsevier, 2012-07-18)
Measurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ ...
Measurement of the polarization amplitudes and triple product asymmetries in the B s 0 → ϕ ϕ decay
(Elsevier, 2012-07-18)
Using 1.0 fb^{-1} of pp collision data collected at a centre-of-mass energy of sqrt{s}=7 TeV with the LHCb detector, measurements of the polarization amplitudes, strong phase difference and triple product ...
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 ...
Observation of the decay B0s→D0φ
(Elsevier, 2013-12)
First observation of the decayB0s→D0φis reported usingppcollision data, corresponding to an inte-grated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. ...
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 ...
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 ...
Observation of CP violation in B ± → D K ± decays
(Elsevier, 2012-06-06)
An analysis of B+ to DK+ and B+ to Dpi+ decays is presented where the D meson is reconstructed in the two-body final states: K+pi-, K+K-, pi+pi- and pi+K-. Using 1.0 fb-1 of LHCb data, measurements of ...
Searches for violation of lepton flavour and baryon number in tau lepton decays at LHCb
(Elsevier, 2013-07-09)
Searches for the lepton flavour violating decay $\tau^-\rightarrow \mu^-\mu^+\mu^-$ and the lepton flavour and baryon number violating decays $\tau^-\rightarrow \bar{p}\mu^+\mu^-$ and $\tau^-\rightarrow ...
