Evidence for the decay B0S→K¯∗0μ+μ−
(Springer, 2018)
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 CP violation using triple product asymmetries in Λ 0b → pK−π+π−, Λ 0b → pK−K+K− and Ξ 0b → pK−K−π+ decays
(Springer, 2018)
A search for CP and P violation using triple-product asymmetries is performed with Λ 0b → pK−π+π−, Λ 0b → pK−K+K− and Ξ 0b → pK−K−π+ decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 fb−1, ...
Measurement of D ±s production asymmetry in pp collisions at √s=7 and 8 TeV
(Springer, 2018)
The inclusive D ±s production asymmetry is measured in pp collisions collected by the LHCb experiment at centre-of-mass energies of √s=7 and 8 TeV. Promptly produced D ±s mesons are used, which decay as D ±s → ϕπ±, with ...

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 ...
Measurement of Z → τ +τ − production in proton-proton collisions at √s=8 TeV
(Springer, 2018)
A measurement of Z → τ +τ − production cross-section is presented using data, corresponding to an integrated luminosity of 2 fb−1, from pp collisions at √s=8 TeV collected by the LHCb experiment. The τ +τ − candidates are ...
Observation of the decay B¯0s→χc2K+K− in the ϕ mass region
(Springer, 2018)
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. ...
Angular moments of the decay Λ0b → Λμ+μ− at low hadronic recoil
