Sažetak
The Large Hadron Collider (LHC) has recently delivered collisions at 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 through the search for anomalous triple gauge couplings. This thesis presents a measurement of the inclusive cross section of the pp -> WGamma -> mu nu Gamma process for phase spaces EGammaT > 15/60/90 GeV and DeltaR(mu ; Gamma)>0.7 using 5.0 fb^-1 of data collected with the CMS detector in 2011. A search for anomalous triple gauge boson WWGamma coupling is performed, resulting in limits on the allowed values of the parameters Deltakappa^Gamma and Lambda^Gamma.
