Photoproduction of Scalar and Pseudoscalar Mesons on a Lepton within the Local Nambu–Jona-Lasinio Modell

摘要

Using the description of the subprocess yr S(P) in terms of local Nambu–Jona-Lasinio model,we calculate the cross sections of photoproduction of scalar and pseudoscalar mesons in high-energy photon-lepton collision processes. The dependence on the transversal momentum and the total cross sections inWeizsacker–Williams approximation are presented.
