Further work * Chao-Hsi Chang (Zhao-Xi Zhang 张肇西) ---Working Group for Physics at Z-factory--- Introduction -Why Z-Factory ?- High Energy Physics (Accelerator) Future Physics Techniques for Z-Factory Accessibility in China (prospect) 2. Physics Topics for Z-Factory (Theoretical considerations only so far) Z boson properties (Precision Test SM New Physics) τ lepton physics (Precision Test SM New Physics) c, b-hadron physics (QCD New Physics) 3. Further Work Deep wide studies (Working Group) A report and a special issue: Science China G, 2010 High Energy Physics (Accelerator vs Non-Accelerator) Future a. ‘Precision’ Frontiers (e+e- collider, high luminosity L): ?-factory (DA?NE) τ-Charm physics (BEPC+BESIII: for 5 and more years) B-factory: Super-B (L = 1035~36cm-2s-1, Japanese) Z-factory (Giga-Z? ILC) b. ‘High Energy’ (New Energy Scale) Frontiers: Tevatron (P-antiP collider, close ‘soon’) LHC (P-P collider, just starting) ILC (e+e- collider, under consideration) CLIC (under studying) etc Physics Techniques for Z-Factory Physics: LEP-I: L0= 2.4 ? 1031cm-2s-1 SLC: L0= 0.6 ? 1031cm-2s-1 Z-Factory: (L =103~4L0 even higher, accessible in techniques) ?1010~11 Z/year, but is it worth enough in physics ?
