In the next order we get: So the expressions for the form factors are: contains both ultraviolet and infrared divergencies. (arXiv:1412.8284, eq.

So it’s not a surprise that Feynman, Schwinger and Tomonaga received the 1965 Nobel Prize in Physics for such a fantastic achievement. QED is staff with experienced, qualified, and certified Medical Physicist, Health Physicists, and Medical Dosimetrists that maintain familiarity with the particular regulations in your area.

So when an electron repels or attracts another electron or positron, what happens is that there is a "force-carrying field" between them. Cambridge, England: Cambridge University Press, 1993.
