Measurement of the γ angle from tree decays at the LHCb experiment

Abstract

An overview of plans for the measurement of γ at the LHCb experiment will be shown. The γ 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 γ. 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 √s = 7 TeV, allowed observations of the first signals of the B decay modes that will be used to perform this measurement.
