Abstract
This Letter presents the complete QED contribution to the electron 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 . We also improve the eighth-order contribution obtaining , which includes the mass-dependent contributions. These results lead to . The improved value of the fine-structure constant [0.25 ppb] is also derived from the theory and measurement of .
