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 ...
Angular analysis of the B0 → K*0e+e− decay in the low-q2 region
(Springer, 2015)
An angular analysis of the B0 → K*0e+e− decay is performed using a data sample, corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and ...
Model-independent measurement of the CKM angle γ using B0 → DK∗0 decays with D → K0S π + π − and K0SK+K−
(Springer, 2016)
A binned Dalitz plot analysis of the decays B 0 → DK ∗0, with D → K 0S π + π − and D → K 0S K + K −, is performed to measure the observables x ± and y ±, which are related to the CKM angle γ and the hadronic parameters ...
Measurement of the properties of the Ξ ∗ 0b baryon
(Springer, 2016)
We perform a search for near-threshold Ξ 0b resonances decaying to Ξ −b π + in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb−1 collected by the LHCb experiment. We observe one ...
Angular analysis and differential branching fraction of the decay B 0s → ϕμ + μ −
(Springer, 2015)
An angular analysis and a measurement of the differential branching fraction of the decay B 0s → ϕμ + μ − are presented, using data corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions recorded by the ...
First observation of the decay B0s → K0S K ∗(892)0 at LHCb
(Springer, 2016)
A search for B0(s) → K0S K ∗(892)0 decays is performed using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected with the LHCb detector at a centre-of-mass energy of 7 TeV. The B 0s → K0S ...
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 ...
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 ...
