N^* Production from e⁺e^- Annihilations

Up to now, the N^* production from e⁺e^- annihilations has been studied only around charmonium region. Charmonium decays to N^*s are analogous to (time-like) EM form factors in that the charm quark annihilation provides a nearly pointlike (ggg) current. Complementary to other sources, such as πN, eN and γN reactions, this new source for N^* spectroscopy has a few advantages, such as an isospin filter and a low spin filter. The experimental results on N^* from e⁺e^- annihilations and their phenomenological implications are reviewed. Possible new sources on N^* production from e⁺e^- annihilations are discussed.
