摘要：
在左右对称模型的背景下，我们研究了中微子less双β衰变（$0νββ$）、违反宇称的莫勒散射和高能碰撞机理之间的相互作用，这些机理源于右手双电荷标量对电子的杨-米尔斯相互作用，这种相互作用可能规避来自带电轻子味违反的严格限制。$0νββ$衰变振幅会从右手惰性中微子获得额外贡献。半衰期在有效场论（EFT）框架下计算，允许对非零左-右手$W$玻色子混合以及交换轻右手中微子的贡献进行更精确的描述。我们发现低能（或高精度）和高能实验之间的相对灵敏度受左右混合影响。另一方面，我们的结果表明碰撞和低能搜索之间的相互作用提供了一种探索无法被$0νββ$衰变实验访问的区域的方法。
英文摘要：
In the context of the left-right symmetric model, we study the interplay of neutrinoless double beta ($0νββ$) decay, parity-violating Møller scattering, and high-energy colliders, resulting from the Yukawa interaction of the right-handed doubly-charged scalar to electrons, which could evade the severe constraints from charged lepton flavor violation. The $0νββ$ decay amplitude receives additional contributions from right-handed sterile neutrinos. The half-life, calculated in the effective field theory (EFT) framework, allows for an improved description of the contributions involving non-zero mixing between left- and right-handed $W$ bosons and those arising from exchanging a light right-handed neutrino. We find that the relative sensitivities between the low-energy (or high-precision) and high-energy experiments are affected by the left-right mixing. On the other hand, our results show how the interplay of collider and low-energy searches provides a manner to explore regions that are inaccessible to $0νββ$ decay experiments.
