Abstract
Different from other multiple top-quark productions, triple top-quark production requires the presence of both flavor violating neutral interaction and flavor conserving neutral interaction. We describe the interaction of triple top-quarks and up-quark in terms of two dimension-6 operators; one can be induced by a new heavy vector resonance, the other by a scalar resonance. Combining same-sign top-quark pair production and four top-quark production, we explore the potential of the 13 TeV LHC on searching for the triple top-quark production.

Combining same-sign top-quark pair production and four top-quark production, we explore the potential of the 13 TeV Large Hadron Collider (LHC) on searching for the triple top-quark production
We argue that the tripletop production is very unique among all the new physics (NP) searching programs related to top-quarks as it is an undoubted signature of flavor violating neutral interaction (FVNI)
Summary
Searching for new physics (NP) beyond the Standard Model (SM) is the major task of the Large Hadron Collider (LHC). The triple top-quark production can be induced in many NP models which have extra heavy scalars or vector resonances with top-quark FVNI interactions [16,17,18] or by effective Lagrangian [19]. In this paper we will assume that such new scalar or vector effects are present, but that the energies available at present and near-future colliders lie below their typical NP scale Λ In this case the characteristics of the new interactions can be probed only through their virtual effects on processes involving SM particles; such effects can be efficiently coded in a model-independent way using the well-studied effective-Lagrangian formalism [20,21,22,23].
