Search for heavy charged gauge bosons in the decay channel W' to \mu\nu with CMS data

Many extensions of the Standard Model of particle physics include the existence of new heavy charged gauge bosons W′. Therefore the search for these new bosons allows to probe several new physics models. In this thesis the search for a W′ in the decay channel W ′ → µν is performed using the complete 2011 dataset of the CMS detector with an integrated luminosity of 4.7 fb−1 at a center of mass energy of 7 TeV. A good agreement between the expectation of the Standard Model and the data is observed, therefore only a new exclusion limit on a potential W′ can be derived. For a W′ with Standard-Model-like couplings the Bayesian limit calculation yields an exclusion of mW′ < 2.4 TeV (95 % CL). The analysis is then combined with the analogous search for W ′ → eν extending the exclusion range to 2.5 TeV. This is the currently best limit for a direct search at a collider experiment. Also the effect of interference between the Standard Model W and the W′ is studied with the help of two models including destructive and constructive interference. Afterwards a model independent exclusion limit on a potential W′ signal cross section is produced, which helps to probe various kinds of models.
