Measurement of the $\gamma$ angle from tree decays at the LHCb experiment

An overview of plans for the measurement of gamma at the LHCb experiment will be shown. The $\gamma$ angle is the least accurately known parameter of the CKM unitary triangle. The LHCb experiment at the CERN LHC aims to perform precision heavy flavour and $CP$ violation measurements, including improving the knowledge of $\gamma$. Focus will be put on methods using B meson decays at the tree level, within the Standard Model framework. The early data recorded by the experiment, from $pp$ collisions at $\sqrt{s}$ = 7 TeV, allowed observations of the first signals of the B decay modes that will be used to perform this measurement.
