CMS Collaboration; Amsler, C; Chiochia, V; Favaro, C; Verzetti, M; Snoek, H; De Visscher, S; Aguiló, E; Schmitt, A; Otyugova, P; Millan, B; Ivova, M; Storey, J (2011). Search for a W′ boson decaying to a muon and a neutrino in pp collisions at √s = 7 TeV. Physics Letters B, 701(2):160-179.

Abstract

A new heavy gauge boson, W′, decaying to a muon and a neutrino, is searched for in pp collisions at a centre-of-mass energy of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 36 pb−1. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the muon–neutrino system. Masses below 1.40 TeV are excluded at the 95% confidence level for a sequential standard-model-like W′. The W′ mass lower limit increases to 1.58 TeV when the present analysis is combined with the CMS result for the electron channel
