Fecha de publicación: | sep-2011 | Editor: | Elsevier | Citación: | Physics Letters B 703(3): 246-266 (2011) | Resumen: | A search for pair-production of first generation scalar leptoquarks is performed in the final state containing an electron, a neutrino, and at least two jets using proton–proton collision data at √s = 7 TeV. The data were collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 36 pb−1. The number of observed events is in good agreement with the predictions for standard model processes. Prior CMS results in the dielectron channel are combined with this electron+ neutrino search. A 95% confidence level combined lower limit is set on the mass of a first generation scalar leptoquark at 339 GeV for β = 0.5, where β is the branching fraction of the leptoquark to an electron and a quark. These results represent the most stringent direct limits to date for values of β greater than 0.05. | Descripción: | 21 páginas, 2 figuras, 4 tablas.-- Open access: This article is distributed under the terms of the Creative Commons Attribution License 3.0.-- CMS Collaboration: et al. | Versión del editor: | http://dx.doi.org/10.1016/j.physletb.2011.07.089 | URI: | http://hdl.handle.net/10261/46574 | DOI: | 10.1016/j.physletb.2011.07.089 | ISSN: | 0370-2693 |
