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

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