Evidence for the decay B0S→K¯∗0μ+μ−
A search for the decay B0S→K¯∗0μ+μ− is presented using data sets corresponding to 1.0, 2.0 and 1.6 fb−1 of integrated luminosity collected during pp collisions with the LHCb experiment at centre-of-mass energies of 7, 8 ...
Search for beautiful tetraquarks in the ϒ(1S)μ+μ− invariant-mass spectrum
The ϒ(1S)μ+μ− invariant-mass distribution is investigated for a possible exotic meson state composed of two b quarks and two b¯ quarks, Xbb¯bb¯. The analysis is based on a data sample of pp collisions recorded with the ...
Angular moments of the decay Λ0b → Λμ+μ− at low hadronic recoil
An analysis of the angular distribution of the decay Λ0b → Λμ+μ− is presented, using data collected with the LHCb detector between 2011 and 2016 and corresponding to an integrated luminosity of approximately 5 fb−1. Angular ...
Observation of the decay B¯0s→χc2K+K− in the ϕ mass region
The B¯0s→χc2K+K− decay mode is observed and its branching fraction relative to the corresponding χc1 decay mode, in a ±15 MeV/c2 window around the ϕ mass, is found to be B(B¯0s→χc2K+K−)B(B¯0s→χc1K+K−)=(17.1±3.1±0.4±0. ...
Measurement of the CKM angle γ using B± → DK± with D → K0Sπ+π−, K0SK+K− decays
A binned Dalitz plot analysis of B± → DK± decays, with D → K 0Sπ+π− and D → K 0SK+K−, is used to perform a measurement of the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle ...
Observation of the decay Λ 0b → ψ(2S)pπ−
The Cabibbo-suppressed decay Λ 0b → ψ(2S)pπ− is observed for the first time using a data sample collected by the LHCb experiment in proton-proton collisions corresponding to 1.0, 2.0 and 1.9 fb−1 of integrated luminosity ...
