Resonances and CP violation in B0s and B¯0s→J/ψK+K− decays in the mass region above the ϕ(1020)
(Springer, 2017)
The decays of B 0s and B¯0s mesons into the J/ψK + K − final state are studied in the K + K − mass region above the ϕ(1020) meson in order to determine the resonant substructure and measure the CP-violating phase, ϕ s , ...
Measurement of CP observables in B± → DK*± decays using two- and four-body D final states
(Springer, 2017)
Measurements of CP observables in B± → DK*± decays are presented, where D denotes a superposition of D0 and D¯0 meson states. Decays of the D meson to K−π+, K−K+, π−π+, K−π+π−π+ and π−π+π−π+ are used and the K*± meson is ...
Measurement of CP violation in B0 → J/ψK 0S and B0 → ψ(2S)K0S decays
(Springer, 2017)
A measurement is presented of decay-time-dependent CP violation in the decays B0 → J/ψ K 0S and B0 → ψ(2S)K 0S, where the J/ψ is reconstructed from two electrons and the ψ(2S) from two muons. The analysis uses a sample of ...
Observation of the decay Λ0b → pK − μ + μ − and a search for CP violation
(Springer, 2017)
A search for CP violation in the decay Λ0b → pK − μ + μ − is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of CP violation. ...
