摘要

我们研究了在标准模型 (SM) 基础上扩展所有在 SM 规范群下不变的维度66算符后的轻子味可观测量。我们计算了辐射轻子衰变μeγ\mu\to e\gammaτμγ\tau \to \mu \gammaτeγ\tau\to e\gamma的完整单圈预测,以及带电轻子密切相关的反常磁矩和电偶极矩,同时考虑了所有能产生轻子味破坏的维度66算符。此外,还考虑了三体味破坏带电轻子衰变τ±μ±μ+μ\tau^\pm \to \mu^\pm \mu^+ \mu^-τ±e±e+e\tau^\pm\to e^\pm e^+ e^- τ±e±μ+μ\tau^\pm \to e^\pm \mu^+ \mu^- τ±μ±e+e\tau^\pm \to \mu^\pm e^+ e^- τ±eμ±μ±\tau^\pm \to e^\mp \mu^\pm \mu^\pmτ±μe±e±\tau^\pm \to \mu^\mp e^\pm e^\pm μ±e±e+e\mu^\pm \to e^\pm e^+ e^-,以及Z0Z^0衰变Z0i+jZ^0\to\ell_i^+\ell_j^-,并考虑了所有树图阶贡献。
