  1. Possible Hints and Search for Glueball Production in Charmless Rare B Decays July 25, 2002 ICHEP 2002, Amsterdam Based on C.K. Chua, WSH and S.Y. Tsai, hep-ph/0204186

  2. f I. Hint ? No Evidence? Underlying Curve (II.) Elsewhere? (IV.) Glueball Bump?(III.) x? George W.S. Hou

  3. II. Possible Dynamics of Underlying 3-body • CLEO’01: Factorized Currents/Current Produced /Isospin Relation • Belle’02: and Extend Idea … Seems to Work Chua, WSH, Tsai, PRD’02 Vector Current gives 60% & Threshold Enhancement hep-ph/0204185, to appear PRD in preparation George W.S. Hou

  4. III. Charmless B Decays & Glueball Search Why Interesting ? • Glueballs Massive  Accessible (Probably) in B Only • Curious: Gluonic Penguin Why No Glue Counterpart ? Absence of ! But … Morningstar and Peardon Glue Rich ! George W.S. Hou

  5. DataAbove(Pre)Postdictions CLEO’98 Resonance b gsgh’ BaBar Not Understood! g*ggh’ ? QCD Anomaly. Caution (A. Kagan): (1S)data indicate form factor small George W.S. Hou

  6. Possible Picture in B Decay: NP? Exciting if True !! Glueball from Charmless B Combine Modes in Analysis ! George W.S. Hou

  7. IV. Other xEvidences and Possible Competition x is Very Controversial “Opponent” Largely However, • Close’s Glueball Filter: • CLEO’s • But, BES … Seem to Give Hints, Too George W.S. Hou

  8. Similar Peak in WA102 PLB’00 at a bit lower Mass (22XX) (calibration) Close’s Glueball Filter George W.S. Hou

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

  10. 20x Expect 10-40 Evts/Mode by End of 2002 [Scale up from BES] Cute if x Emerges From CLEO George W.S. Hou

  11. Less Prominent But, BES … (at PIC’02) PRL’96 7x Data George W.S. Hou

  12. Conclusion • Charmless B Decays: Possible Glueball Search Ground? - Heavy Enough to Produce Glueballs - Penguins are Gluon Induced - The h’ Enigma: Rates Too Large and Not Understood! Glue Rich Indication. - “Possible” Hint in 3-body Charmless … - Lot’s of Data/Growing Fast! • CLEO (1S),  All Have Tantalizing Hints and Search Potential Glueballs May (or May Not) Emerge in a Year, in these channels George W.S.
