自 20 世纪 30 年代以来，人们就知道虚拟中微子-反中微子对的交换会产生远程力。最近的工作研究了在原子和核光谱中观察这种相互作用的可能性。在本文中，我们开发了一种新方法来计算非相对论费米子之间的自旋无关2-中微子交换势（2-NEP），然后将其推广到中微子质量状态的混合，假设核子-核子、核子-轻子和轻子-轻子相互作用的正常和反转质量排序。最后，我们展示了涉及轻子的 2-NEP 对中微子混合矩阵中 $CP$ 破坏相的依赖性。
It has been known since the 1930s that long-range forces can arise from the exchange of virtual neutrino-antineutrino pairs. Recent work has investigated the possibility of observing this interaction in atomic and nuclear spectroscopy. In this paper we develop a new approach to calculate spin-independent 2-neutrino exchange potentials (2-NEPs) between non-relativistic fermions, which is then generalized to incorporate the mixing of neutrino mass states assuming normal and inverted mass ordering for nucleon-nucleon, nucleon-lepton, and lepton-lepton interactions. Finally, we exhibit the dependence of the 2-NEP involving leptons on the $CP$-violation phase in the neutrino mixing matrix.
