Non-diffractive production of strange axial vector mesons

Abstract

Presents a simple model for non-diffractive axial vector meson production at intermediate energies. Data on the analogous pseudoscalar production processes are used to predict the production properties of the A1(JPC=1++) and B(1+-) SU(3) nonets. A unitary, coupled-channel formalism then allows one to predict the s, t and m2 dependence of the Q-like enhancements which are observed in the K rho and K* pi channels produced in charge and hypercharge exchange processes. Detailed predictions for forthcoming experiments are made. Existing data are in qualitative agreement with the model.
