论文摘要
muon，电子和两个光子的接触相互作用可以促进衰减$μ\ toeγγ$，也可以将穆恩转化为核的电场中的电子。我们计算$μ\至e $转换率，并表明，对于涉及组合$ ff \ propto | \ vec | \ vec {e} |^2 $的操作员的系数（而不是$ f \ tilde {f} {f} \ propto \ propto \ vec \ vec \ vec {e} in} in \ cdot \ cdot \ vec \ vent ofer the ofertion \ contrient forigh比$μ\ toeγγ$的结合。
Contact interactions of a muon, an electron and two photons can contribute to the decay $μ\to e γγ$, but also to the conversion of a muon into an electron in the electric field of a nucleus. We calculate the $μ\to e$ conversion rate, and show that for the coefficients of operators involving the combination $FF \propto |\vec{E}|^2$ (as opposed to $F\tilde{F} \propto \vec{E} \cdot \vec{B}$), the current bound on $μ\to e$ conversion is more sensitive than the bound on $μ\to e γγ$.
