论文摘要
我们研究了尺寸 - 五个Lepton-number违反操作员的影响，与两个相同的弱玻色子相关，$ \ ell^\ pm \ ell^{\ prime \ pm} w^\ mp w^\ mp w^\ mp $，在当前和未来的中子振荡，lepton-number违反稀有过程和高级过程中，且高级胶水效果。这些操作员可以包含有关微小中微子质量起源的重要信息，该信息与所谓的温伯格操作员无关。我们通过中微子振荡数据检查了对操作员系数的限制。还可以通过使用数据来研究Lepton数字违规过程，例如中微子双β衰减和$μ^ - $ - $ - $ e^+$ conversion来研究系数上的上限。这些操作员也可以通过在高能量强大的强子对撞机（例如大型强子对撞机）的高能量强生collider中搜索Lepton-number违反DiLepton生产的Lepton-number。我们发现这些运算符可以通过这些当前和将来的实验进行大量探测。
We study impacts of dimension-five lepton-number violating operators associated with two same-sign weak bosons, $\ell^\pm \ell^{\prime \pm} W^\mp W^\mp$, on current and future experiments for neutrino oscillation, lepton-number violating rare processes and high-energy collider experiments. These operators can contain important information on the origin of tiny neutrino masses, which is independent of that from the so-called Weinberg operator. We examine constraints on the coefficients of the operators by the neutrino oscillation data. Upper bounds on the coefficients are also investigated by using the data for processes of lepton number violation such as neutrinoless double beta decays and $μ^-$-$e^+$ conversion. These operators can also be directly tested by searching for lepton-number violating dilepton production via the same-sign W boson fusion process at high-energy hadron colliders like the Large Hadron Collider. We find that these operators can be considerably probed by these current and future experiments.
