Search for Heavy Right-Handed W Bosons and Heavy Right-Handed Neutrinos Produced by 7 TeV pp Collisions Inside the CMS Detector

This paper describes a search for signals from the production of right-handed WRbosons and heavy neutrinos N ( = µ) that arise naturally in the SUC (3) ⊗ SUL (2) ⊗SUR (2) ⊗ U (1) left-right symmetric model. The search was performed using data collected from proton-proton collisions produced by the Large Hadron Collider at a center√of-mass energy of s = 7 TeV, and occurring inside the Compact Muon Solenoid experiment. The data was collected during the 2010 running period and corresponds toa total integrated luminosity of L = 36 pb−1 . No excess over expectations from Standard Model processes is observed. For models with exact left-right symmetry (the samecoupling in the right sector), an exclusion region is established in the two-dimensionalparameter space (MWR , MN ) that extends to MWR = 1360 GeV/c2 , exceeding priorlimits set by the Tevatron proton-antiproton collider.Prospects for discovery or exclusion of these particles in the year 2011 using a projected 1 fb−1 total integrated luminosity are presented.In addition, a method of precision timing of calorimetric deposits in the hadroncalorimeter of CMS is discussed.
