Measurement of the CP-violating phase ϕ from B s 0 → J / ψ π + π − decays in 13 TeV pp collisions
© 2019 The Author Decays of Bs0 and B‾0s mesons into J/ψπ+π− final states are studied in a data sample corresponding to 1.9 fb−1 of integrated luminosity collected with the LHCb detector in 13 TeV pp collisions. A time-dependent amplitude analysis is used to determine the final-state resonance contr...
