| Abstract: A search for new physics in final states with an electron or a muon and a low mass neutrino is presented.This analysis uses 2012 data corresponding to an integrated luminosity of 20 fb−1, collected using the CMS detector in pp collisions at a centre-of-mass energy of 8 TeV at the LHC. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the lepton-neutrino system. Mass exclusion limits up to 3.35 TeV at 95\% CL for a SM-like W′ boson are determined. These results are also interpreted in the framework of split universal extra dimensions and exclusion limits on Kaluza--Klein W2KK states are set. Limits are also set on the model where interference between a potentially left-handed W′ and the SM W boson occurs. Another reinterpretation is performed in terms of compositeness, which would manifest itself as a four-fermion contact interaction, setting a limit on the new contact interaction scale Λ of 13.0(10.9) TeV for the electron(muon) channel. | ||
