[HTML][HTML] Total Born cross section of e+ e−-pair production by an electron in the Coulomb field of a nucleus
RN Lee, AA Lyubyakin, VA Smirnov - Physics Letters B, 2024 - Elsevier
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 …
