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

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