Contribution of the t-channel $N^{\ast }(1535)$ exchange for the $p\bar{p}\to \varphi \varphi$ reaction

Abstract

Since the $N^{\ast }(1535)$ resonance was found to have large coupling to the strangeness due to its possible large $s\bar{s}$ component, we investigate the possible contribution of the t-channel $N^{\ast }(1535)$ exchange for the $p\bar{p}\to \varphi \varphi$ reaction. Our calculation indicates that the new mechanism gives very significant contribution for the energies above 2.25 GeV and may be an important source for evading the Okubo-Zweig-Iizuka rule in the $\varphi$ production from $N\bar{N}$ annihilation.
