Total Born cross section of e+e−-pair production by an electron in the Coulomb field of a nucleus
We calculate the total Born cross section of the e+e−-pair production by an electron in the field of a nucleus (trident process) using the modern multiloop methods. For general energies we obtain the cross section in terms of converging power series. The threshold asymptotics and the high-energy asy...
