CSIC ORCID; Chatrchyan, S.; CMS Collaboration | Fecha de publicación: | 2012 | Editor: | Springer Nature | Citación: | Journal of High Energy Physics: 23 (2012) | Resumen: | A search for a new heavy gauge boson W' decaying to an electron or muon, plus a low mass neutrino, is presented. This study uses data corresponding to an integrated luminosity of 5.0 inverse femtobarns, collected using the CMS detector in pp collisions at a centre-of-mass energy of 7 TeV at the LHC. Events containing a single electron or muon and missing transverse momentum are analyzed. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the lepton-neutrino system, and upper limits for cross sections above different transverse mass thresholds are presented. Mass exclusion limits at 95% CL for a range of W' models are determined, including a limit of 2.5 TeV for right-handed W' bosons with standard-model-like couplings and limits of 2.43--2.63 TeV for left-handed W' bosons, taking into account their interference with the standard model W boson. Exclusion limits have also been set on Kaluza--Klein W[KK] states in the framework of split universal extra dimensions. | Descripción: | 31 páginas, 5 figuras, 2 tablas.-- CMS Collaboration: et al.-- Open Access: This article is distributed under the terms of the Creative Commons Attribution License. | Versión del editor: | http://dx.doi.org/10.1007/JHEP08(2012)023 | URI: | http://hdl.handle.net/10261/53179 | DOI: | 10.1007/JHEP08(2012)023 | E-ISSN: | 1029-8479 |
