SEARCH FOR HIGH MASS RESONANCES DECAYING TO TAU PAIRS AT THE CMS EXPERIMENT

High-mass states such as heavy gauge bosons (Z'), Kaluza-Klein resonances, and gravitons, all of which decay into di-lepton states, are predicted by several physics models. In this thesis a general search for high mass resonances decaying to tau lepton pairs at the Large Hadron Collider (LHC) i...
