我们报告了μ介子十阶QED项的计算结果$\mathrm{<trans\; data-src="g">克</trans>}<trans\; data-src="-">-</trans>\mathrm{<trans\; data-src="2">2</trans>}$。我们的结果是${\mathrm{<trans\; data-src="a">一</trans>}}_{\mathrm{<trans\; data-src="\mu ">\mu </trans>}}^{<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="10">10</trans>}<trans\; data-src=")">)</trans>}<trans\; data-src="=">=</trans>\mathrm{<trans\; data-src="753.29">753.29</trans>}$（1.04）单位为$<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="\alpha ">\alpha </trans>}<trans\; data-src="/">/</trans>\mathrm{<trans\; data-src="\pi ">\pi </trans>}{<trans\; data-src=")">)</trans>}^{\mathrm{<trans\; data-src="5">5</trans>}}$，比领先的算术估计值663（20）大约4.5 s.d。我们还提高了的八阶QED项的精度${\mathrm{<trans\; data-src="a">一</trans>}}_{\mathrm{<trans\; data-src="\mu ">\mu </trans>}}$，获取${\mathrm{<trans\; data-src="a">一</trans>}}_{\mathrm{<trans\; data-src="\mu ">\mu </trans>}}^{<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="8">8</trans>}<trans\; data-src=")">)</trans>}<trans\; data-src="=">=</trans>\mathrm{<trans\; data-src="130.8794">130.8794</trans>}$（63）单位为$<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="\alpha ">\alpha </trans>}<trans\; data-src="/">/</trans>\mathrm{<trans\; data-src="\pi ">\pi </trans>}{<trans\; data-src=")">)</trans>}^{\mathrm{<trans\; data-src="4">4</trans>}}$.新的QED贡献是${\mathrm{<trans\; data-src="a">一</trans>}}_{\mathrm{<trans\; data-src="\mu ">\mu </trans>}}<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="QED">量化宽松政策</trans>}<trans\; data-src=")">)</trans><trans\; data-src="=">=</trans>\mathrm{<trans\; data-src="116">116</trans>}\text{<trans data-src="\hspace{0.17em}">\hspace{0.17em}</trans>}\mathrm{<trans\; data-src="584">584</trans>}\text{<trans data-src="\hspace{0.17em}">\hspace{0.17em}</trans>}\mathrm{<trans\; data-src="718">718</trans>}\text{<trans data-src="\hspace{0.17em}">\hspace{0.17em}</trans>}\mathrm{<trans\; data-src="951">951</trans>}\text{<trans data-src="\hspace{0.17em}">\hspace{0.17em}</trans>}<trans\; data-src="(">(</trans>\mathrm{<trans\; data-src="80">80</trans>}<trans\; data-src=")">)</trans><trans\; data-src="\times ">\times </trans>{\mathrm{<trans\; data-src="10">10</trans>}}^{<trans\; data-src="-">-</trans>\mathrm{<trans\; data-src="14">14</trans>}}$，这并没有解决标准模型预测和测量之间存在的差异${\mathrm{<trans\; data-src="a">一</trans>}}_{\mathrm{<trans\; data-src="\mu ">\mu </trans>}}$.
