Interference Between Light and Heavy Neutrinos for $0\nu\beta\beta$ Decay in the Left-Right Symmetric Model

Understand

Neutrinoless double-beta decay is proposed as an important low energy phenomenon that could test beyond the Standard Model physics.

• There are several potentially competing beyond the Standard Model mechanisms that can induce the process.
• It thus becomes important to disentangle the different processes.
• In the present study we consider the interference effect between the light left-handed and heavy right-handed Majorana neutrino exchange mechanisms.
