摘要

We study the leptonic decays of ground and excited states of vector charmonia in the framework of Bethe-Salpeter equation. We calculate the electronic and muonic decay widths for ground and excited states of vector charmonia which are of relevance to cross section calculations of exclusive processes involving charmonium production.
