The Direct Production of Electron Pairs in Nuclear Emulsion by 100 and 200 GeV Protons
It is proposed to study the direct production of electron pairs produced when a high energy proton interacts with the Coulomb field of a nucleus. This process occurs at fourth order in quantum electrodynamics. This phenomena, called trident production when the incident particle is an electron, is characterized by a single incident primary track and three emerging tracks. Accelerator experiments on direct pair production by protons have not been previously reported, due to the small cross-sections at energies less than 100 GeV. However, at an energy of 100 GeV the cross-section for the direct creation of electron pairs by protons in emulsion is about 10{sup -25}cm{sup 2}.
