  1. The Riches of Charmless Rare B Decays George W.S. Hou(侯維恕) National Taiwan University June 7, 2002 2nd BCP Workshop @ NTU

  2. I. Introduction: The 1997-1999 Episode 1997  1999: Data Increase from 3 fb-1 to 10 fb-1 Bonanza Years Set In ! 1998 -Inclusive h:Anomaly & New Physics(bsg Dipole) - New Physics CPV? (bsg Dipole) 1999- Large g and EWP - Factorization, T-P Interference & g > 90º [  Multimode Fit for g, Hou-Smith-Wuerthwein] 2000 -Oddities and d (rescattering) Phase 2001 -Abelian Flavor & CPV -Rare Baryonic I gained personally the following PRLs: Able Collaborators Kp/pp Future: Light-cone of Present & Past George W.S. Hou

  3. Outline Probably can’t cover all… I. Introduction: The 1997-1999 Episode II. Strong Penguins: Mesonic * Kp/pp rescatter ? * hKProblem?  New/Exotic III. Strong Penguins: Baryonic * From B  pp(bar)K to B xK * Comment on 3-body IV. EM & EW Penguins * Abelian Flavor/SUSY: b  sg and Bs System * B Kl+l− : 4th Generation? V. Conclusion: Richness Growing George W.S. Hou

  4. In Late 1999 Conjecture (Hou-Yang, PRL’00): (rescatter) II. Strong Penguins: Mesonic * Kp/pp Rescatter ? 2002 Large g & Large d Rescatter ? George W.S. Hou

  5. Approach: Rescatter Onlyin Final State Rescattering Topologies Formalism Developed from D0h0 PRD’02 George W.S. Hou

  6. Some Numerical Results ppRates! CPV measurement Important Controlling If Belle Correct Controlling ! Too Large ? ! Belle/BaBar Average Possible ! OK Too Small ? Will See ! George W.S. Hou

  7. b g sgh’ Case for New Dynamics inh Modes Still Not Understood After ~ 5 yrs h’K Rate Large: / m(Xs) Spectrum “3-body” h’Xs Rate Large BaBar Resonance George W.S. Hou

  8. Anomaly g* g gh’? Glueball Support of F.F.?[Hou-Tseng] For:Both CLEO/BaBar Spectrum[Belle Soon?] Possible to account for Strength & Spectrum All Other Models tend to Peak at Lower Mass Against:Form Factor Argument a Too Suppressed (Kagan) mP George W.S. Hou

  9. a Further Challenge from Ugggg*ggggh’ Kagan hep-ph/0201313 (HF’01 Talk) Fast h’from U 3 Form Factor Fall-offs Too Large ‘93 z = 2E_h’/m_U (4-body Decay MC) (a), (b), (c): Slow, Intermed. Fast F.F. Fall-off Did Not Consider Hou-Tseng F.F. Conjecture Await CLEO-c George W.S. Hou

  10. Further Elucidation 3g System Very Massive George W.S. Hou

  11. III. Strong Penguins: Baryonic* From B  pp(bar)K to B xK This is a Great Expt/TH Interface Story • 1998-99 Semi-sabbatical at BNL/Cornell: CLEO2-body Rare Baryon Limits  Start Work • Draft Ready (w/ Soni) 2/1999 …. CLEO D*pn PRL’00  Submit PRL [Restart Rare Baryon Field] • Suggest Minzu Wang start on Rare baryon 4/01 Work on D*pn Model [S.Y. Tsai talk] PRD’02 Hint of Rare Baryon 7’01  Easy Paper on rpn PLB’02 • Discovery of pp(bar)K 9/01 (Belle internal:)  Extension Work [S.Y. Tsai talk] Submit PRD Further Stimulation on B  Glueball George W.S. Hou

  12. No Evidence ? Elsewhere ? x? George W.S. Hou

  13. Lower Bound Naively CLEO chose “Conservative” 20x Expect 10-40 Evts/Mode by End of 2002 [Scale up from BES] Cute if x Emerges From CLEO George W.S. Hou

  14. (LEAR) Narrower If B-W +Underlying [Palano, Frascati ’99] Too broad ? Maybe There Afterall ! George W.S. Hou

  15. Close’s Glueball Filter Similar Peak in Published WA102 at Slightly Lower Mass (22XX) George W.S. Hou

  16. Gluonic Counterpart of Penguin b -> sqq Possible Picture in B Decay: NP? Appear By Summer ? Exciting if True !! Glueball from Charmless B George W.S. Hou

  17. Conclusion/Outline I. The Richness of ’97 - ’99: Episode I II. Strong Penguins: Mesonic * Kp/pp rescatter ? * hKProblem? [  New/Exotic ] III. Strong Penguins: Baryonic * From B  pp(bar)K to B xK [* Comment on 3-body] [IV. EM & EW Penguins * Abelian Flavor/SUSY: b  sg and Bs System * B Kl+l− : 4th Generation?] V. Conclusion: Richness Growing Just in Hadronic Entering CPV & NP Probes Soon George W.S. Hou

  18. bsg gluonic dipole: cg Hybrid from Charmless ? Two Off-shoot Thoughts on h |cg| = 1, 0.5, 0.25 sis NP Phase K? BaBarPublishedBellePublished sin2bsin2f1 Kg ? Sensitive Probe [w/ K.C. Yang] [w/ Chua and Sen] George W.S. Hou
