Abstract

I report on an updated combination of all currently available tree-level measurements of the CKM angle $\gamma$ from LHCb. This combination currently gives LHCb's most precise value of $\gamma = (73^{+9}_{-10})^\circ$ obtained from $B\to DK$ -like decays. For the first time in a single experiment, the uncertainty has dropped below $10^\circ$ . When using $B\to D\pi$ decays in addition, the situation becomes more difficult to interpret.
