Abstract

Charmonium spectroscopy with Kogut-Susskind valence quarks are carried out for quenched QCD at $I^^{2} = 6.0$ and for two-flavor full QCD at $I^^{2} = 5.7$ . Results for 1P--1S mass splitting and estimates of $I^\pm_{M S}^{(5)} (m_{Z})$ are reported. Problems associated with flavor breaking effects and finite size effects of $1 P$ states are discussed.
