In this work we investigate the production and signatures of doubly-charged
particles at the Large Hadron Collider. We start with the Standard Model
particle content and representations and add generic doubly-charged exotic
particles. We classify these doubly-charged states according to their spin,
considering scalar, fermionic and vectorial fields, and according to their
SU(2)L representation, being chosen to be either trivial, fundamental, or
adjoint. We write the most general interactions between them and the Standard
Model sector and study their production modes and possible decay channels. We
then probe how they can most likely be observed and how particles with
different spin and SU(2)L representations could be possibly distinguished.Comment: 18 pages, 8 figures, 1 table; version accepted by Phys.Rev.
