Heavy-heavy-light quark potential in two approaches

Abstract

We perform the first study about the heavy-heavy-light quark potential in lattice QCD and a potential model. We find that the inter-two-quark confining force is reduced by valence quark motional effects compared to the string tension.Comment: Talk given at YITP International Symposium: Fundamental Problems in Hot and/or Dense QCD, Kyoto, Japan, 3-6 March 200
