Description
In the context of the left-right symmetric model, we study the interplay of the neutrinoless double beta ($0\nu\beta\beta$) decay, parity-violating Møller scattering, and high-energy colliders, resulting from the Yukawa interaction of the right-handed doubly-charged scalar to electrons, which could evade the severe constraints from charged lepton flavor violation. The half-life $\onbb$ decay calculated in the effective field theory (EFT) framework allows for an improved description of the contributions with a non-zero left-right mixing and light right-handed neutrino.
We find that the sensitivities of the low-energy (or high-precision) and high-energy experiments are complementary to each other. The reach of parity-violating Møller scattering in the MOLLER experiment is stronger than those of future ton-scale $0\nu\beta\beta$-decay for TeV scale right-handed neutrino if the left-right mixing is negligible. On the other hand, for a non-zero left-right mixing, the constraints set by the MOLLER experiment become complementary to future ton-scale $0\nu\beta\beta$-decay experiments as well as direct searches and precision measurements at high-energy colliders.
