Radiative decay into γP of the low lying axial - vector mesons

We evaluate the radiative decay into a pseudoscalar meson and a photon of the whole set of the axial-vector mesons dynamically generated from the vectorpseudoscalar meson (V P ) interaction. We take into account tree level and loop diagrams coming from the axial-vector decay into a vector and a pseudoscalar meson. We find a large span for the values of the radiative widths of the different axial-vector mesons. In particular, we evaluate the radiative decay into Kγ of the two K1(1270) states, recently claimed theoretically, and discuss the experimental values quoted so far on the assumption of only one state.
