Complementary studies on $N^*$ from $e^+e^-$, $pp$ and $p\bar p$ collisions

Abstract

Complementary to the conventional experimental studies on NN^* from πN\pi N and γ()N\gamma^{(*)}N reactions, the e+ee^+e^-, pppp and ppˉp\bar p collisions can give novel insights into these NN^* resonances. While the e+ee^+e^- collisions through production and decay of vector charmonium ψ\psi provide a nice isospin filter for a simultaneously study of NN^*, Δ\Delta^*, Λ\Lambda^*, Σ\Sigma^* and Ξ\Xi^*, the pppp collisions should be the best place for producing those Δ++\Delta^{*++} with large coupling to ρ+p\rho^+p though ppnΔ++pp\to n\Delta^{*++} reaction, and the ppˉp\bar p collisions should be the best place for looking for those NN^* with large coupling to σN\sigma N.
