主 题：Z factory D0 mesons mixing B factory
摘 要：The possibility of studying D 0-D 0 mixing at a giga-Z linear collider Z factory where 10 9 hadronic Z 0 decays can be accumulated is *** discuss the sensitivity for the measurements of neutral D mixing *** results are compared to those attainable at B *** find that the typical decay length of the neutral D mesons at Z factory is about 10 times larger than that at B *** addition,the resolution of the vertex detector of a giga-Z factory is 2-3 times better than that of B *** proper time resolution at Z factory is about 20-30 times better than that at B *** the determination of the mixing parameters at a giga-Z factory is more precise.
