Vectorlike leptons and inert scalar triplet: Lepton flavor violation, g-2, and collider searches

Indexación: Scopus.We investigate simplified models involving an inert scalar triplet and vectorlike leptons that can account for the muon g-2 anomaly. These simplified scenarios are embedded in a model that features W' and Z' bosons, which are subject to stringent collider bounds. The constraints coming from the muon g-2 anomaly are put into perspective with collider bounds, as well as bounds coming from lepton flavor violation searches. The region of parameter space that explains the g-2 anomaly is shown to be within reach of lepton flavor violation probes and future colliders such as HL-LHC and HE-LHC. © 2020 authors.

Dead or alive? Implications of the muon anomalous magnetic moment for 3-3-1 models

Indexación: Scopus.We have witnessed a persistent puzzling anomaly in the muon magnetic moment that cannot be accounted for in the Standard Model even considering the existing large hadronic uncertainties. A new measurement is forthcoming, and it might give rise to a 5σ claim for physics beyond the Standard Model. Motivated by it, we explore the implications of this new result to five models based on the SU(3)C×SU(3)L×U(1)N gauge symmetry and put our conclusions into perspective with LHC bounds. We show that previous conclusions found in the context of such models change if there are more than one heavy particle running in the loop. Moreover, having in mind the projected precision aimed by the g-2 experiment at FERMILAB, we place lower mass bounds on the particles that contribute to muon anomalous magnetic moment assuming the anomaly is otherwise resolved. Lastly, we discuss how these models could accommodate such anomaly in agreement with current bounds. © 2020 The Author(s) Learn about these Topicshttps://www-sciencedirect-com.recursosbiblioteca.unab.cl/science/article/pii/S0370269320304925?via%3Dihu
