摘要：

The contribution to the (g - 2) of a lepton of mass M from the light-light graphs with a loop lepton of mass m is evaluated analytically in sixth order QED perturbation theory for arbitrary values of the ratio of the masses, and the cases of physical relevance are then derived from the general expression. In particular, the analytical value of the (g - 2) of the mu lepton from light-light graphs with an electron loop is presented; the result is in excellent agreement with the most precise numerical evaluations already existing in the literature.
