Abstract:
In Asaka et al (2021 Phys. Rev. D 103 , 015014), Asaka, Ishida and Tanaka put forward an interesting possibility that the neutrinoless double beta decay can be hidden in the minimal seesaw model with the two right-handed neutrinos having a hierarchical mass structure: the lighter one is lighter enough than the typical Fermi-momentum scale of nuclei while the heavier one is sufficiently heavy to decouple from the neutrinoless double beta decay. Then, in the basis where the mass matrices of the charged leptons and right-handed neutrinos are diagonal, for some particular texture of the Dirac neutrino mass matrix M D , the neutrinoless double beta decay can be hidden. In this paper, on top of this specified model, we study the interesting scenario that M D further obeys the TM1 symmetry or μ – τ reflection symmetry which are well motivated by the experimental results for the neutrino mixing parameters.
