摘要Within the framework of chiral effective field theory, we study various electromagnetic processes with light vector resonances: K*(892) -> K gamma, e(+)e(-) -> K* (892)K, and the omega pi gamma* form factors. With two multiplets of vector resonances being introduced, we fit the decay widths of K*0 -> K-0 gamma, K*(+) -> K+gamma, and the pertinent measurements from the e(+)e(-) -> K*(+/-)(892)K--/+ cross sections, such as moduli and relative phases between the isoscalar and isovector components from the BABAR Collaboration, together with the omega pi form factors from the NA60, SND, and CLEO collaborations. The values of resonance couplings, masses and widths of the excited vector states rho' and phi' are then determined. The omega'-phi' mixing angle is discussed and turns out to be quite different from the ideal mixing case. Three sources of SU(3) symmetry breaking effects in the Gamma(K* -> K gamma) decays are identified and analyzed in detail.
