Constraining CKM $\gamma$ angle at LHCb
The current combination of all available tree-level measurements of the CKM angle gamma at LHCb is reported. It includes results obtained from time independent analyses of B+ -> DK+ and of B0 -> DK∗0 decays; and from a time-dependent analysis of Bs0 -> DsK decays. The results represent the...

Sumario: | The current combination of all available tree-level measurements of the CKM angle gamma at LHCb is reported. It includes results obtained from time independent analyses of B+ -> DK+ and of B0 -> DK∗0 decays; and from a time-dependent analysis of Bs0 -> DsK decays. The results represent the world's best single-experiment determination of gamma. The first observation of the Bs->Ds*K decay and the first observation and amplitude analysis of B- -> D+K-pi- are also reported. In addition to these tree measurements, the estimation of gamma from charmless B meson decay, sensitive to loops contribution, is presented. |
