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 !

Not Understood!
gggh ? QCD Anomaly. Caution (A. Kagan)
?(1S) data indicate form factor small
6
Possible Picture in B Decay
NP?
Exciting if True !! Glueball from Charmless B
Combine Modes in Analysis !

IV. Other x Evidences and Possible Competition

• x is Very Controversial
• Opponent Largely
• However,
• Closes Glueball Filter
• CLEOs
• But, BES

Seem to Give Hints, Too

from BES
Cute if x Emerges From CLEO

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
• - Lots 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
