论文摘要
如果核的中性双重β衰减由短范围的相互作用主导，我们会研究一些后果。为了说明我们的结果，我们假设这种衰减主要是通过涉及两次W实量交换的短距离相互作用进行的，并将自己局限于仅包括新的标量，而没有新的量规交互。对于中微子质量问题，我们建议通过采用主动的光中微子的主要含量为dirac块，而新标量诱导的小主要质量使它们变得伪造（Quasi） - 迪拉克颗粒。中微子的这一特殊方面可以在下微中微子振荡实验和/或中微子望远镜中检测到。如果是这样，这将在中微子双β衰减与中微子物理学之间开设新的联系。我们还指出了新的物理信号，例如可以在强子山子中探索的高电荷标量状态。特别是，我们发现高能量E^ - E^ - 对撞机将在测试Lepton数字违规的起源方面非常有用，这补充了中微子双重衰变研究。
We investigate some consequences if neutrinoless double beta decays of nuclei are dominated by short range interactions. To illustrate our results, we assume that such decays proceed mainly through short range interactions involving two-W-bosons exchanges and confine ourselves to only include new scalars without new gauge interactions for SM fermions. For the neutrino mass problem we propose to solve it by adopting that the active light neutrinos have predominantly Dirac masses and the small Majorana masses induced by the new scalars render them pseudo(quasi)-Dirac particles. This particular aspect of neutrinos may be detectable in the next generation of neutrino oscillation experiments and/or neutrino telescopes. If so this opens a new connection between neutrinoless double beta decays and neutrino physics. We also noted the new physics signals such as high charged scalar states that can be explored in hadron colliders. In particular, we find that a high energy e^- e^- collider will be very useful in testing the origin of lepton number violation which complements neutrinoless double decays studies.
