Amplitude analysis and branching fraction measurement of ¯Bos → J/ψ K+K−
(American Physical Society, 2013-04-08)
An amplitude analysis of the final state structure in the ¯¯¯B0s→J/ψK+K− decay mode is performed using 1.0 fb−1 of data collected by the LHCb experiment in 7 TeV center-of-mass energy pp collisions ...
Determination of γ and −2βs from charmless two-body decays of beauty mesons
(Elsevier, 2015-02-04)
Using the latest LHCb measurements of time-dependent CP violation in the B-s(0) -> K+K- decay, a U-spin relation between the decay amplitudes of B-s(0) -> K+K- and B-0 -> p(+)p(-) decay processes allows ...
Measurement of the inclusive phi cross-section in pp collisions at sqrt(s) = 7 TeV.
(Elsevier, 2011-07)
The cross-section for inclusive Φ meson production in pp collisions at a centre-of-mass energy of s=7 TeV has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section ...
First Observation of CP Violation in the Decays of B0s Mesons
(American Physical Society, 2013-05-30)
Using pp collision data corresponding to an integrated luminosity of 1.0 fb−1 and collected by LHCb in 2011 at a center-of-mass energy of 7 TeV, we report the measurement of direct CP violation in ...
Observation of a Resonance in B+→K+μ+μ− Decays at Low Recoil
(American Physical Society, 2013-09-10)
A broad peaking structure is observed in the dimuon spectrum of B+→K+μ+μ− decays in the kinematic region where the kaon has a low recoil against the dimuon system. The structure is consistent with ...
Observation of the suppressed ADS modes B± → [π± K∓ π+ π−] DK± and B± → [π± K∓ π+ π−] Dπ
(Elsevier, 2013-06-10)
An analysis of B±→DK±B±→DK± and B±→Dπ±B±→Dπ± decays is presented where the D meson is reconstructed in the four-body final state K±π∓π+π−K±π∓π+π−. Using LHCb data corresponding to an integrated luminosity ...
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 ...
Evidence for CP Violation in Time-Integrated D0→h−h+ Decay Rates
(American Physical Society, 2012-03-12)
A search for time-integrated CP violation in D0→h−h+ (h=K, π) decays is presented using 0.62 fb−1 of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the ...
Measurement of the lifetime of the Bc+ meson using the Bc+→ J/ψπ+ decay mode
(Elsevier, 2015-03-06)
The difference in total widths between the Bc+ and B+mesons is measured using a data sample corresponding to an integrated luminosity of 3.0 fb-1collected by the LHCb experiment in 7 and 8 TeV centre-of-mass ...
Measurement of the ¯B0s Meson Lifetime in D+sπ− Decays
(American Physical Society, 2014-10-24)
We present a measurement of the ratio of the ¯B0s meson lifetime, in the flavor-specific decay to D+sπ−, to that of the ¯B0 meson. The pp collision data used correspond to an integrated luminosity of ...
