The Compact Muon Solenoid (CMS) Experiment operates at the Large Hadron Collider (LHC) which is the highest energy particle accelerator in the world. CMS is a general purpose detector designed to investigate a wide range of physics, including the search for the Higgs boson. The measurement of photon production in the CMS experiment is crucial since it represents an irreducible background for many new physics searches, such as decay of Higgs to two photon, supersymmetry and extra-dimensions. The study of beam halo contamination is important for the correct measurement of photon production. This thesis presents a way to identify and remove this contamination by using the timing and the shower shape of the photons.
