Abstract
A bstract We study the contribution of a heavy right-handed Majorana neutrino to neutrinoless double beta decay (0 νββ ) via four-fermion effective interactions of Nambu-Jona-Lasinio (NJL) type. In this physical scenario, the sterile neutrino contributes to the nuclear transition through gauge, contact, and mixed interactions. Using the lower limit on the half-life of 0 νββ from the KamLAND-Zen experiment, we then constrain the effective right-handed coupling between the sterile neutrino and the W boson: $$ {\mathcal{G}}_R^W $$ GRW . Eventually, we show that the obtained bounds are compatible with those found in the literature, which highlights the complementarity of this type of phenomenological study with high-energy experiments.
摘要研究了重右手马约拉纳中微子通过Nambu-Jona-Lasinio (NJL)型四费米子有效相互作用对无中微子双β衰变(0 νββ)的贡献。在这种物理情况下，无菌中微子通过规范、接触和混合相互作用促进核跃迁。利用KamLAND-Zen实验中0 νββ的半衰期下限，我们约束了不育中微子和W玻色子之间的有效右手耦合:$$ {\mathcal{G}}_R^W $$ G R W。最后，我们证明所得到的界与文献中发现的界是相容的，这突出了这种类型的现象学研究与高能实验的互补性。
