Abstract

The Large Hadron Collider (LHC) has recently delivered collisions at a center of mass energy of 7 TeV and has therefore allowed for the first time to test the validity of the Standard Model (SM) at TeV scale. The precise measurement of electroweak processes constitute a central part of this program. Diboson processes, in which pairs of electroweak bosons are produced, provide in particular a good opportunity to test SM at these energies. They also allow to seek indirectly for new physics... More through the search for anomalous triple gauge couplings. This thesis presents a measurement of the inclusive cross section of the pp → Wγ → μνγ process for phase spaces EγT > 15/60/90 GeV and ΔR(μ, γ) > 0.7 using 5.0 fb-1 of data collected with the CMS detector in 2011. A search for anomalous triple gauge boson WWγ coupling is performed, resulting in limits on the allowed values of the parameters Δκγ and λγ. Less
