Evidence of N*(1535) resonance contribution in the pn->dϕreaction

Abstract

The N*(1535) resonance contributions to the pn->dϕreaction are evaluated in an effective Lagrangian model. The π-, η-, and ρ-meson exchange are considered. It is shown that the contributions from π- and ρ-meson exchange are dominant, while the contribution from η-meson exchange is negligibly small. Our theoretical results reproduce the experimental data of both total cross section and angular distribution well. This is another evidence that the N*(1535) resonance has large s\bar{s} component leading to a large coupling to Nϕ, which may be the real origin of the OZI rule violation in the \piN and pN reactions.
