Abstract

The results of measuring the ratio R = Y(φπ⁺π^-)/Y(ωπ⁺π ^- ) for antiproton annihilation at rest in a gaseous and a liquid hydrogen target are presented. It was found that the value of this ratio increases with the decrease of the dipion mass, which demonstrates the difference between the φ and ω production mechanisms. An indication of the momentum transfer dependence of the apparent OZI rule violation for the φ production from the ³S₁ initial state was found.
