Angular analysis of charged and neutral B → Kμ + μ − decays
(Springer, 2014)
The angular distributions of the rare decays B + → K + μ + μ − and B0→K0Sμ+μ− are studied with data corresponding to 3fb−1 of integrated luminosity, collected in proton-proton collisions at 7 and 8 TeV centre-of-mass ...
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 ...
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 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 ...
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 ...
Measurement of CP asymmetry in B0s → D ∓s K± decays
(Springer, 2014)
We report on measurements of the time-dependent CP violating observables in B 0s → D ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating ...
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 ...
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 ...
Precise measurements of the properties of the B1(5721)0,+ and B *2(5747)0,+ states and observation of B+,0π−,+ mass structures
(Springer, 2015)
Invariant mass distributions of B+π− and B0π+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb−1 of pp collision data, recorded by the LHCb ...
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 ...
