Nonresonant Background in Isobaric Models of Photoproduction of η-Mesons on Nucleons

  • Published:
Russian Physics Journal Aims and scope

Within the framework of isobaric models of pseudoscalar meson photoproduction, the nonresonant background of photoproduction of η-mesons on nucleons is investigated as a function of energy. A bound on the magnitude of the pseudoscalar coupling constant of the η-meson with a nucleon is obtained: g 2ηNN /4π ≤ 0.01, and a bound on vector meson exchange models is also obtained.
