Abstract
The formation of q (q) over bar resonances lying on the leading Regge trajectories in the (N) over bar N system is studied in the quark-gluo n string model. The model predicts strong suppression of the decays of q (q) over bar states into (N) over bar N pairs in relation to two-me son modes. Our analysis shows that the contributions of the resonances f(4)(2050) (I(G)J(PC) = 0(+)4(++)), rho(5)(2240) (I(G)J(PC) = 1(+)5(- -)) and f(6)(2510) (I(G)J(PC) = 0(+)6(++)) to the processes of two-mes on (N) over bar N annihilation((p) over bar p --> pi pi, (K) over bar K...) are about 1% of the corresponding experimental integrated cross sections.
