First measurement of the differential branching fraction and CP asymmetry of the B ± → π ± μ + μ − decay
(Springer, 2015)
The differential branching fraction with respect to the dimuon invariant mass squared, and the CP asymmetry of the B ± → π ± μ + μ − decay are measured for the first time. The CKM matrix elements |V td | and |V ts |, and ...
Differential branching fraction and angular analysis of Λ 0b → Λμ+μ− decays
(Springer, 2015)
The differential branching fraction of the rare decay Λ 0b → Λμ+μ− is measured as a function of q2, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to ...
Determination of the branching fractions of B0S → D∓S K ∓ and B0 → D −S K +
(Springer, 2015)
Measurements are presented of the branching fractions of the decays B 0S → D ∓S K ∓ and B 0 → D −S K + relative to the decays B 0S → D −S π + and B 0 → D − π +, respectively. The data used correspond to an integrated ...
Differential branching fractions and isospin asymmetries of B → K (*) μ + μ − decays
(Springer, 2014)
The isospin asymmetries of B → Kμ + μ − and B → K * μ + μ − decays and the partial branching fractions of the B 0 → K 0 μ + μ −, B + → K + μ + μ − and B + → K *+ μ + μ − decays are measured as functions of the dimuon mass ...
Measurement of CP violation parameters and polarisation fractions in B0s→J/ψK∗0 decays
(Springer, 2015)
The first measurement of CP asymmetries in the decay B0s→J/ψK∗(892)0 and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an ...
First observation and measurement of the branching fraction for the decay B 0s → D ∗s ∓ K ±
(Springer, 2015)
The first observation of the B 0s → D ∗s ∓ K ± decay is reported using 3.0 fb−1 of proton-proton collision data collected by the LHCb experiment. The D ∗s ∓ mesons are reconstructed through the decay chain D ∗s ∓ → γD ...
Observation of the Λ0b → J/ψ pπ − decay
(Springer, 2014)
The first observation of the Cabibbo-suppressed decay Λ 0b → J/ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. A prominent signal is ...
Search for the decay B0s→D¯0f0 (980)
(Springer, 2015)
A search for B0s→D¯0f0(980) decays is performed using 3.0 fb1− of pp collision data recorded by the LHCb experiment during 2011 and 2012. The f0(980) meson is reconstructed through its decay to the π+π− final state in the ...
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 ...
