摘要: 目前，正负电子湮灭过程的核子激发态N^*产生的实验数据主要来自于粲偶素能区。粲偶素衰变到核子激发态过程类似于其类时电磁形状因子测量过程，正反粲夸克短程湮灭提供了近乎于点源的胶子强子化过程。与γN，eN，πN反应互补，这一新的N^*产生源具有同位旋和低自旋筛选的优势。综述了正负电子湮灭过程的核子激发态N^*产生的实验情况和相关的唯象进展，同时讨论未来发展的一些新方向，如正负电子湮灭过程的核子激发态N^*产物的一些新来源等。

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.
