EXO-200 is a single phase liquid xenon detector designed to search for neutrinoless double-beta decay of $^{136}$Xe. Here we report on a search for various Majoron-emitting modes based on 100 kg$\cdot$yr exposure of $^{136}$Xe. A lower limit of $T^{^{136}Xe}_{1/2} >1.2 \cdot 10^{24}$ yr at 90% C.L. on the half-life of the spectral index = 1 Majoron decay was obtained, corresponding to a constraint on the Majoron-neutrino coupling constant of $|< g^{M}_{ee} >|<$ (0.8-1.7)$\cdot$10$^{-5}$.

Probing scalar-neutrino and scalar-dark-matter interactions with PandaX-4T
PandaX-4T reports the first direct spectral search for scalar-mediated neutrino self-interactions in 136Xe double beta decay, setting new upper limits for mediator masses below 2 MeV/c².
