Jan. 19, 2004 @ Super BGeorge W.S. Hou 5 Totsuka sensei’s Charge to Super-KEKB... Considering all these research programs other than the B factory, the Considering all these research programs other than the B factory, the funding for the luminosity upgrade of a B-factory is not an easy task for KEK, and for other laboratories, too. All I can say at this point is that I need more good results like the recent one in order to impress MEXT (funding agency) about how important the super-B factory program is. One thing I like to hear from you is, though it is a nasty question, One thing I like to hear from you is, though it is a nasty question, what you will do once a consensus is made to globally build the LC; whether you will join the LC or you will still be 100% involved in the super-B factory.... super-B factory.... A no-nonsense guy! BELLE’s new result on asymmetry in the B Ks Theme “David & Goliath” Redux ? Large NP CPV Phase w/ Crisp Measurement HL5 @ Izu ’n I agree w/ him...

Hou 6 Large NP CPV Phase w/ Crisp Measuremen t S K s Sign Anomaly K * Polarization Anomaly “Belle” SK*0(Ks)SK*0(Ks)SK*0(Ks)SK*0(Ks) “BaBar” Confession: We’ve been saying for years “ICPV in B K s is a great place to search for New Physics”. It was lip service. The mindset was “Precision Tests”. So, S K s < 0, for 2nd year, came as a shocker. Kagan (SSI 2002)“P Conserving”... Chua, WSH, Nagashima 03WSH, Nagashima (to appear)

Jan. 19, 2004 @ Super BGeorge W.S. Hou 21 Tuning for S K s ≲ 0, S ’K s ~ S K s Possible S K s S K s ≲ 0 prefers lower -plane S ’K s ➯ S ’K s ≅ sin2 B d as well ! Lower gluino mass S K s Lower gluino mass lowers S K s Hadronic Parameters CP phase enters B → K s via Lower q 2, and/or larger S K s ➯ Larger | S K s | ∴ Prefer to keep gluino mass above 500 GeV (L.E. Constraints) Could ≲ /2 be it? Noticed also by Khalil & Kou ’03 [Murayama et al. ’03] 0.5 TeV Preferred

Pursued B 0 K 1 (1270) etc. instead... S K s So, BaBar’s S K s came as a shocker. ’course, had large(r) Si (than Belle) or so I thought... Nakao san will show eff. vs Si size Invest in Larger Si ! Confession II S K s difficult N.B. S K s difficult for hadronic for hadronic
