Relativistic quark model predictions for meson radiative transition form factors

Abstract

Within a relativistic quark model predictions for form factors of ω→ πγ, a 1→ πγ, a 2→ πγ, b 1→ πγ transitions at 0 ⩽| K 2|⩽ 3 GeV 2 are made, which turned out to be significantly different from each other and from VDM predictions. The contributions of these form factors to the cross sections of ω, a 1, a 2, b 1 meson electroproduction via one-pion exchange are found and it is shown that their K 2 dependence is quite different for these mesons which is of great interest for experimental research.
