“…To solve the above two problems of naturalness and neutrino oscillation, models have been proposed to incorporate neutrino masses into some scenarios with the VLTs, such as ones that include lepton-number violation between scalar triplet and lepton doublet within the Littlest Higgs scenario [78], as well as other Little Higgs [79][80][81][82][83][84][85][86][87][88][89], Composite Higgs [90][91][92][93][94], Top Seesaw [95][96][97] and Higgs Inflation models [98]. A common feature of these new models is that VLTs and heavy Majorana neutrinos are predicted, which leads to a new decay mode of VLT through the mediation of heavy Majorana neutrinos.…”

The Standard Model is a successful theory but lack of a mechanism for neutrino mass generation as well as a solution to the naturalness problem. In the models that are proposed to simultaneously solve the two problems, heavy Majorana neutrinos and top partners are usually predicted that can lead to a new decay mode of the top partner mediated by the heavy Majorana neutrinos:T → b W + → b + + q q . In this paper, we will study the observability of such a new signature via the pair production process of top partner pp → T T → 2b + ± ± + 4j in a model independent way. By performing Monte-Carlo simulation, we present the 2σ exclusion limits of the top partner mass and mixing parameters at the HL-LHC.

Probing a new decay of vector-like top partner mediated by heavy Majorana neutrino via single production

Models beyond the Standard Model have been proposed to simultaneously solve the problems of naturalness and neutrino mass, in which heavy Majorana neutrinos and vector-like top partners are usually predicted. A new decay channel of the top partner mediated by the heavy Majorana neutrino can thus appear: T → b W + → b + + q q . We study in this paper the observability of this decay process through single production of the top partner at the 14 TeV LHC: pp → T / T +jets→ b/ b + µ ± µ ± +jets. 2σ exclusion bounds on the top partner mass and mixing parameters are given by Monte-Carlo simulation, which surpass those from the search through VLT pair production in the mass range of m T > 1.3 TeV.
