Photoproduction of scalar and pseudoscalar mesons on a lepton within the local Nambu-Jona-Lasinio model

Abstract

Using the description of the subprocess $\gamma {\gamma }^{\ast }\to S(P)$ 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 collisions processes. The dependence on the transversal momentum and the total cross sections in Weizsaecker-Williams approximation are presented.
