Measurements of CKM angle $\gamma$ in LHCb
Year: 2024
Type: conference-paper
Abstract: In these proceedings, the current status of measurements of the CKM angle $\gamma$ at LHCb is presented. The combination of the current measurements by LHCb to date is discussed, as well as results that are not yet included in the combination. This includes a first measurement of $\gamma$ using the $B^\pm\to Dh^\pm$ decay with $D\to K^+K^-\pi^+\pi^-$, where $h = \pi, K$. This analysis uses charm strong-phase parameters predicted by a model, but it will be updated when direct measurements of these parameters is available. In addition, two model-independent measurements of $\gamma$ using the charm decays $D\to K_S^0\pi^+\pi^-$ and $D\to K_S^0K^+K^-$ are shown for the first time, using the channels $B^0\to DK^*$ and $B^\pm\to D^*h^\pm$. Finally, future prospects are discussed.
