First study of the CP-violating phase and decay-width difference in B0s→ψ(2S)φ decays
(Elsevier, 2016)
A time-dependent angular analysis of B0s→ψ(2S)φdecays is performed using data recorded by the LHCb experiment. The data set corresponds to an integrated luminosity of 3.0 fb−1collected during Run1 of the LHC. The CP-violating ...
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 ...
Differential branching fraction and angular moments analysis of the decay B 0 → K +π− μ + μ − in the K∗0,2(1430)0 region

A study of the decay D0→K−π+μ+μ−is performed using data collected by the LHCb detector in proton–proton collisions at a centre-of-mass energy of 8TeV, corresponding to an integrated luminosity of 2.0fb−1. Decay candidates ...
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 ...
Measurement of the CKM angle γ from a combination of LHCb results
(Springer, 2016)
A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B + → DK +, B 0 → DK ∗0, B 0 → DK +π− and B + → DK +π+π− tree-level decays. In addition, ...
Measurements of long-range near-side angular correlations in √sNN=5TeV proton-lead collisions in the forward region
