Description

Majoron ($J$) is a feebly-interacting axion-like particle that can realize type-I seesaw mechanism, which also leads to flavor violating processes (FVP). We revisit prospects of sub-GeV majoron at intensity frontier experiments. We show that FVP allow to probe the majoron mass region \sim 100 MeV to 1 GeV, complementary to astrophysical bounds and dedicated experiments probing FVP. We also study muon-beam experiments, where for the majoron lighter than muon, the \mu \to e J decays can put limits competitive with those set by supernovae.
