  We have studied the branching ratios of doubly charged Higgs bosons at the
LHC using a version of the SU(3)$_L\otimesU(1)_N$ electroweak model. At the end
of this work we have made a very simple plotting comparating the total cross
section of this model using Drell-Yan, gluon-gluon fusion and Left-right
symmetric model.
