Description
The left-right symmetric model (LRSM) is a well-motived scenario to accommodate the tiny neutrino masses, e.g. via the type-I seesaw. The mixing of heavy neutrinos in the LRSM could induce lepton flavor violating (LFV) couplings of the $SU(2)_R$-breaking neutral scalar $H_3$, which arise at the 1-loop level via the heavy $W_R$ boson and the heavy neutrinos. When $H_3$ is light, say at or below the GeV scale, such LFV signals can be searched for in the high-intensity experiments and the astrophysical observations. It turns out that the right-handed scale $v_R$ is severely constrained, up to the $10^6$ GeV scale, well above the direct high-energy collider limits.
