“…There is a similar study for bilepton pair production in e + e − [22] and a work of the production of just one double-charged vector bilepton [23]. The production of double-charged Higgs was studied in the left-right symmetric model [24] and in the 3-3-1 model with heavy leptons for e + e − colliders [25], photon-photon collisions [26], and hadron colliders [27,28]. Here we compare the production of a pair of gauge bileptons (Y ±± ) with that of a pair of scalar bilpetons (S ±± 1 ) to evaluate the ratio between the production cross sections.…”

We study the double-charged vector-bilepton pair production and double-charged scalar-bilepton pair production via+ X, where Y and S 1 are vector and scalar bileptons respectively, in the framework of the minimal version of the 3-3-1 model. We compute the photon, Z, and Z ′ s-channel contributions for the elementary process of bilepton scalar pair production, and to keep the correct unitarity behavior for the elementary qq interaction, we include the exotic quark t-channel contribution in the vector-bilepton pair production calculation. We explore a mass range for Z ′ and we fix the exotic quark mass within the experimental bounds. In this model, the vector-bilepton mass is directly related to M Z ′ and we consider scalar mass values around the vector-bilepton mass.We show that the total cross section for vector-bilepton production is 3 orders of magnitude larger than for scalar pair production for √ s = 7 TeV and 14 TeV and we obtain the number of events for the proposed LHC luminosities as a function of the bilepton mass. In addition we present some invariant mass and transverse momentum distributions. When comparing these distributions we observe quite different behavior providing the determination of the bilepton nature. We conclude that one can disentangle the production rates and that the LHC can be capable of detecting these predicted particles as a signal for new physics.

“…The cross section for the CLIC, which integrated luminosity will be of the order of 3 Â 10 6 pb À1 =yr, is restricted by the mass of the doubly charged Higgs, because for v ¼ 1000ð1500Þ and 9 ¼ À1:2 the acceptable masses are up to m H AEAE ' 1107ð1651Þ GeV, see Ref. [4]. Taking this into account we obtain for bremstrahlung distribution, see Fig.…”

“…It was shown that the simplest 3-3-1 model, which is also the simplest chiral extension of the SM, is in triplet representation of SUð3Þ of the matter field, so it incorporates the DCHBs naturally and the results in Refs. [3,4] indicate a sufficient number of events required for establishing the signal. Research has been done with DCHBs and a lower limit of 141 (114) GeV for their masses are obtained by Hera and Fermilab, respectively [5].…”

Masses and signals of the production of Doubly charged Higgses (DCH) in the framework of the supersymmetric reduced minimal 3-3-1 model (SUSYRM331) are investigated. In the DCH sector, we prove that there always exists a region of the parameter space where the mass of the lightest DCH is in order of O(100) GeV even when all other new particles are very heavy. The lightest DCH mainly decays to two same-sign leptons while the dominated decay channels of the heavy DCHs are those decay to heavy particles. We analyze each production cross section for e + e − → H ++ H −− as a function of a few kinematic variables, which are useful to discuss the creation of the DCHs in the e + e − colliders as a signal of new physics beyond the Standard Model. The numerical study shows that the cross sections for creating the lightest DCH can reach values of few pbs. The two other DCHs are too heavy, beyond the observable range of experiments. The lightest DCH may be detected by the International Linear Collider (ILC) or the Compact LInear Collider (CLIC) bysearching its decay to a same-sign charged lepton pair. PACS numbers: 11.15.Ex, 12.60.Fr, 13.66.Fg H ± 1 behaving the same as those in the MSSM. More explicitly, they couple with W and Z boson the in same way as those in the MSSM, especially in the large limit of the SU(3) L and soft SUSY breaking scales, which is exactly the valid condition of the SUSYRM331.So the total contribution to the ρ parameter of these SUSYRM331 Higgses is nearly the
