Within the effective Lagrangian approach, we study the p p → ψη (ψ ≡ ψ(3686), J/ψ) reaction at the low energy where the contributions from nucleon pole and low-lying nucleon resonances, N(1520), N(1535) and N(1650) are considered. All the model parameters are determined with the help of current experimental data on the decay of ψ → p pη. Within the model parameters, the total and differential cross sections of the p p → ψη reaction are predicted. We show that the relative phases between different amplitudes of different nucleon resonance will change significantly the angular distributions of the pp → ψη reaction. Therefore, we conclude that these reactions are suitable to study experimentally the properties of the low lying nucleon resonance and the reaction mechanisms. We hope that these theoretical calculations could be tested by the future experiments.

“…1 and Fig. 2, we construct the effective Lagrangians with the covariant L-S (obital-spin) coupling scheme [33,34,[47][48][49]. The couplings of pseudoscalar meson (M = τ · π, η or η ′ ) to S 11 , P 11 and P 13 resonances (R) are:…”

“…In recent years, plenty of information on nucleon resonances [1] has been obtained by a wealth of phenomenological studies on numerous data of the πN , γN , eN reactions and pN collisions [23][24][25][26][27][28][29][30][31][32][33][34][35]. However, despite a great deal of theoretical and experimental efforts, our knowledge of nucleon resonances around 2.0 GeV is still scarce because of the presence of many resonances and opening channels in this energy region.…”

We are aiming to study the J/ψ → ppη ′ decay in an isobar model and the effective Lagrangian approach. After a careful exploration of the contributions of the S11(1535), P11(1710), P13(1900), S11(2090) and P11(2100) resonances, we conclude that either a subthreshold resonance or a broad P -wave state in the near threshold range seems to be indispensable to describe present data of the πN → η ′ N . Furthermore, at least one broad resonance above η ′ N threshold is preferred. With this detailed analysis, we could give the invariant mass spectrum and Dalitz plot of the J/ψ → ppη ′ decay for the purpose of assisting the future detailed partial wave analysis. It is found that the J/ψ → ppη ′ data are useful for disentangling the above or below threshold resonant contribution, though it still further needs the differential cross section data of πN → η ′ N to realize some of the resonant and the non-resonant contribution. Our results are enlightening for the η ′ N production mechanism and the properties of the nucleon resonances with the mass around 2.0 GeV.

Phenomenological study on the reactions

Abstract: We extend our recent phenomenological study of pN → N N ππ reactions to thepN →N N ππ reactions for anti-proton beam momenta up to 3.0 GeV within an effective Lagrangian approach.
