Measurement of the ratio of branching fractions B(B+c→J/ψK+)/B(B+c→J/ψπ+)
The ratio of branching fractions RK/π≡B(B+c→J/ψK+)/B(B+c→J/ψπ+) is measured with pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 TeV and 8 TeV, corresponding to an integrated luminosity ...
Angular analysis of B0→D∗−D∗+s with D∗+s→D+sγ decays
The first full angular analysis of the B0→D∗−D∗+s decay is performed using 6 fb−1 of pp collision data collected with the LHCb experiment at a centre-of-mass energy of 13 TeV. The D∗+s→D+sγ and D*− → D¯¯¯¯0π− vector meson ...
Observation of the decay B0s → η c ϕ and evidence for B 0s → η c π + π −
A study of B0s → η c ϕ and B0s → η c π + π − decays is performed using pp collision data corresponding to an integrated luminosity of 3.0 fb−1, collected with the LHCb detector in Run 1 of the LHC. The observation of the ...
Test of lepton universality with B0 → K *0 ℓ + ℓ − decays
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B 0 → K *0 μ + μ − and B 0 → K *0 e + e − decays, RK∗0, is presented. The K *0 meson is reconstructed in the final state K ...
Updated branching fraction measurements of B0(s) → K0Sh+h′ − decays
The charmless three-body decays B 0( s) → K0Sh+h′ − (where h(′) = π, K) are analysed using a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1. The branching ...
