Constraints on the Timeon Model

TL;DR

This paper investigates the constraints on the timeon model, proposing a suppression mechanism for FCNCs, and finds the timeon mass must exceed 151 GeV to satisfy experimental bounds, extending the analysis to leptons.

Contribution

It introduces a small parameter to suppress FCNCs in the timeon model and determines the lower bound on the timeon mass, extending the model to leptons.

Findings

Timeon mass must be >151 GeV to avoid FCNC constraints.

A small parameter effectively suppresses FCNCs.

Model extension to leptons analyzed with relevant constraints.

Abstract

The timeon model recently proposed by Friedberg and Lee has a potential problem of flavor changing neutral currents (FCNCs) if the mass of the timeon is small. In order to avoid, we introduce a small dimensionless parameter to suppress FCNCs. Even in this case, we find that the timeon mass must be larger than 151 GeV to satisfy all the constraints from processes involving FCNCs in the quark sectors. We also extend the timeon model to the lepton sector and examine the leptonic processes.
