# Tenth-order QED contribution to the electron g-2 and an improved value of the fine structure constant.

@article{Aoyama2012TenthorderQC, title={Tenth-order QED contribution to the electron g-2 and an improved value of the fine structure constant.}, author={Tatsumi Aoyama and Masashi Hayakawa and Toichiro Kinoshita and Makiko Nio}, journal={Physical review letters}, year={2012}, volume={109 11}, pages={ 111807 } }

This letter presents the complete QED contribution to the electron g-2 up to the tenth order. With the help of the automatic code generator, we evaluate all 12,672 diagrams of the tenth-order diagrams and obtain 9.16 (58)(α/π)(5). We also improve the eighth-order contribution obtaining -1.9097 (20)(α/π)(4), which includes the mass-dependent contributions. These results lead to a(e)(theory)=1,159,652,181.78(77)×10(-12). The improved value of the fine-structure constant α(-1)=137.035999173 (35…
