CSIC ORCID | Palabras clave: | Hadron-Hadron Scattering | Fecha de publicación: | jul-2011 | Editor: | Springer Nature | Citación: | Journal of High Energy Physics 07: 098 (2011) | Resumen: | A search for groups of collimated muons is performed using a data sample collected by the CMS experiment at the LHC, at a centre-of-mass energy of 7TeV, and corresponding to an integrated luminosity of 35 pb−1. The analysis searches for production of new low-mass states decaying into pairs of muons and is designed to achieve high sensitivity to a broad range of models predicting leptonic jet signatures. With no excess observed over the background expectation, upper limits on the production cross section times branching fraction times acceptance areset, ranging from 0.1 to 0.5 pb at the 95% CL depending on event topology. In addition, the results are interpreted in several benchmark models in the context of supersymmetry with a new light dark sector exploring previously inaccessible parameter space. | Descripción: | 15 páginas, 4 figuras.-- Open Access.
