标题： Dissecting Lepton Number Violation in the Left-Right Symmetric Model: $0νββ$ decay, Møller scattering, and collider searches

摘要： 在左-右对称模型的背景下，我们研究了无中微子双贝塔衰变（$0\nu\beta\beta$）、宇称破坏的M{\o }勒散射和高能对撞机之间的相互作用，这些相互作用源于右手上双荷标量与电子之间的杨氏相互作用，这可能规避带电轻子味破坏所带来的严重约束。 $0\nu\beta\beta$衰变振幅从右手上标 sterile 中微子中获得额外贡献。 在有效场论（EFT）框架下计算的半衰期允许改进描述涉及左-右手$W$玻色子之间非零混合以及由交换轻右手中微子引起的贡献。 我们发现，低能（或高精度）实验和高能实验之间的相对灵敏度受到左右混合的影响。 另一方面，我们的结果显示了对撞机和低能搜索之间的相互作用如何提供一种探索对$0\nu\beta\beta$衰变实验不可及区域的方法。 显示英文摘要

摘要： In the context of the left-right symmetric model, we study the interplay of neutrinoless double beta ($0\nu\beta\beta$) decay, parity-violating M{\o}ller 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 $0\nu\beta\beta$ 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 $0\nu\beta\beta$ decay experiments.
