TL;DR
This paper discusses how to identify lepton number violating scalar particles, especially doubly-charged ones, at the LHC by analyzing their leptonic decay patterns to determine their electroweak properties.
Contribution
It introduces a method to determine the electroweak quantum numbers of lepton number violating scalars through their decay signatures at the LHC.
Findings
Doubly-charged scalars can be identified via leptonic decays.
Electroweak quantum numbers can be inferred from decay patterns.
Method applicable to scalars mediating type II see-saw.
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 electro-weak quantum numbers can be determined through their leptonic decays in pair and single production.
