Distinguishing between lepton number violating scalars at the LHC

By Francisco del Águila Giménez, Mikael Chala, Arcadi Santamaria and Jose Wudka

Abstract

Scalars with lepton number violating interactions decaying into lepton pairs, as those mediating the see-saw of type II, always include doubly-charged components. If these are observed at the LHC, their electroweak quantum numbers can be determined through their leptonic decays in pair and single production.This work has been supported in part by the Ministry of Economy and Competitiveness (MINECO), under the grant numbers FPA2006-05294, FPA2010-17915 and FPA2011- 23897, by the Junta de Andalucía grants FQM 101 and FQM 6552, by the “Generalitat Valenciana” grant PROMETEO/2009/128, and by the U.S. Department of Energy grant No. DE-FG03-94ER40837. M.C. is supported by the MINECO under the FPU program
