Its gauge group is isomorphic to the circle group, and the use of renormalization to remove divergences in this theory was formulated by Dyson, who also showed the equivalence of its operator and diagram forms.
This theory predicts the existence of both a u-channel diagram and t-channel diagram in Moller scattering. Its gauge group is isomorphic to the circle group, and the use of renormalization to remove divergences in this theory was formulated by Dyson, who also showed the equivalence of its operator and diagram forms. Precision tests of it involve checking the correlation between independent calculations of the fine structure constant, and this theory is used to explain the deviation of the electron's magnetic moment from 2. It predicts virtual electron-positron pair production as the source of vacuum polarization, and one-loop effects in it give rise to the Lamb shift. Charged particles exchange photons in, for 10 points, name this extremely accurate abelian gauge theory developed by Schwinger, Tomonaga, and Feynman.
