LHCb: Measurement of Gamma from $B \rightarrow DK$ Decays

The angle $\gamma$ of the CKM Unitarity Triangle is the only one that can be measured directly at tree level. Direct measurements of $\gamma$ constrain the triangle and any deviations from unity may be an indication of new physics. This poster presents three analyses that look at a variety of $B \rightarrow DK$ decays, whose information is then combined to perform a $\gamma$ measurement. The best fit value of $\gamma$ is ${71.1^{+16.1}_{-15.2}} ^\circ$.
