Vector- and scalar-bilepton pair production in hadron colliders

Abstract

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.

Probing 3-3-1 models in diphoton Higgs boson decay

“…Also, it has to be said that the 3-3-1 model can explain the top forward/backward asymmetry recently measured at the Tevatron, as was shown in Ref. [38].…”

A 331 WIMPy dark radiation model

“…This model is a compelling alternative to the SM with a smoking gun signature given by the presence of charged gauge bosons and scalars, as well as a spectrum of particles whose phenomenological aspects have been investigated extensively [23][24][25][26][27][28][29][30][31]. This model is also consistent with all electroweak bounds, while offering plausible explanations to many open problems in particle physics, such as dark matter [32][33][34] and the number of particle generations [35].…”

Implications of the CDF $ t\bar{t} $ forward-backward asymmetry for hard top physics

“…Several works have interpreted the recent CDF measurement of A tt 450 within specific models of new physics [10,11,12,13,14,15,16,17,18,19,20,21,22,23]. Similarly, model-independent analyses were performed [24,25,26] and new physics models were invoked [27,28,29,30,31,32,33,34,35,36,37,38,39,40,41] to explain earlier D0 and CDF measurements of the inclusive asymmetry [5,6].…”
