First observations of the rare decays B + → K + π + π − μ + μ − and B +→ ϕK + μ + μ −
(Springer, 2014)
First observations of the rare decays B + → K + π + π − μ + μ − and B +→ ϕK +μ+μ− are presented using data corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment at centre-of-mass energies ...
Measurements of the B +, B 0, B0s meson and Λ0b baryon lifetimes
(Springer, 2014)
Measurements of b-hadron lifetimes are reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. Using the exclusive decays ...
Study of forward Z + jet production in pp collisions at √s = 7 TeV
(Springer, 2014)
A measurement of the Z(→ μ + μ −) + jet production cross-section in pp collisions at a centre-of-mass energy √s = 7 TeV is presented. The analysis is based on an integrated luminosity of 1.0 fb−1 recorded by the LHCb ...
Searches for Λ0b and Ξ0b decays to K0Spπ− and K0SpK− final states with first observation of the Λ0b→K0Spπ− decay
(Springer, 2014)
A search for previously unobserved decays of beauty baryons to the final states K0spπ- and K0 spK- is reported. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb- of pp collisions. ...
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)
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 collision data, corresponding ...
Search for CP violation using T-odd correlations in D 0 → K + K −π+π− decays
(Springer, 2014)
A search for CP violation using T-odd correlations is performed using the four-body D 0 → K + K −π+π− decay, selected from semileptonic B decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 ...
