Abstract:

In this talk, I consider the minimal extension of the standard model by introducing two Majorana right-handed neutrinos whose masses are assumed to be less than the electroweak scale. In this model, one of the nuclei which in principle can cause the neutrinoless double beta decay would not provide any lepton number violating signals due to contribution from one of right-handed neutrinos. Even in this case, however, I show that such information can give us some hints to search for right-handed neutrinos in the future experiments. I also discuss the impact of the difference among nuclei.
