Observation of the Resonant Character of the Z(4430)− State
(American Physical Society, 2014-06-04)
Resonant structures in B0→ψ′π−K+ decays are analyzed by performing a four-dimensional fit of the decay amplitude, using pp collision data corresponding to 3 fb−1 collected with the LHCb detector. The ...
Observation of Photon Polarization in the b→sγ Transition
(American Physical Society, 2014-04-22)
This Letter presents a study of the flavor-changing neutral current radiative B±→K±π∓π±γ decays performed using data collected in proton-proton collisions with the LHCb detector at 7 and 8 TeV center-of-mass ...
Study of the kinematic dependences of Λ 0b production in pp collisions and a measurement of the Λ 0b → Λ +c π − branching fraction
(Springer, 2014-08-26)
The kinematic dependences of the relative production rates, fΛ0b/fd, of Λ 0b baryons and B 0 mesons are measured using Λ 0b → Λ +c π − and B¯¯¯¯0 →D+π− decays. The measurements use proton-proton ...
