Fecha de publicación: | jul-2011 | Editor: | Elsevier | Citación: | Physics Letters B 701(4): 204-223 (2011) | Resumen: | A search for pair-produced bottom-like quarks in pp collisions at √s = 7 TeV is conducted with the CMS experiment at the LHC. The decay b' →tW is considered in this search. The b' ¯b' →tW−¯tW+ process can be identified by the distinctive signature of trileptons and same-sign dileptons. With a data sample corresponding to an integrated luminosity of 34 pb−1, no excess above the standard model background predictions is observed and a b' quark with a mass between 255 and 361 GeV/c2 is excluded at the 95% confidence level. | Descripción: | 20 páginas, 3 figuras, 2 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.2011.05.074 | URI: | http://hdl.handle.net/10261/46533 | DOI: | 10.1016/j.physletb.2011.05.074 | ISSN: | 0370-2693 |
