Description
The process γ*γ → σ is investigated in the framework of the SU(2) x SU(2) chiral NJL model, where γ*γ are photons with the large and small virtuality, respectively, and σ is a pseudoscalar meson. The form factor of the process is derived for arbitrary virtuality of γ* in the Euclidean kinematic domain. The asymptotic behavior of this form factor resembles the asymptotic behavior of the γ*γ → π form factor
Abstract (Russian)
Процесс γ*γ → σ изучен в рамках киральной SU(2) x SU(2)-модели Намбу-Иона-Лазинио, где γ*γ - фотоны с большой и малой виртуальностью, соответственно. Асимптотическое поведение формфактора сходно с асимптотическим поведением формфактора процесса γ*γAdditional details
