New data on OZI rule violation in $\overline{P}P$ annihilation at rest
The results of a measurement of the ratio R =3D Y(phi pi+ pi-) / Y(omega = pi+ pi-) for antiproton annihilation at rest in a gaseous and in a liquid hydrogen target are presented. It was found that the value of this ratio increases with the decreasing of the dipion mass, which demonstrates the diffe...
