The Majoron at two loops

High Energy Physics - Phenomenology 2019-11-20 v2

Abstract

We present singlet-Majoron couplings to Standard Model particles through two loops at leading order in the seesaw expansion, including couplings to gauge bosons as well as flavor-changing quark interactions. We discuss and compare the relevant phenomenological constraints on Majoron production as well as decaying Majoron dark matter. A comparison with standard seesaw observables in low-scale settings highlights the importance of searches for lepton-flavor-violating two-body decays +\ell \to \ell' +Majoron in both the muon and tau sectors.
