  1. 0-+ Klempt No eta(1295) eta(1440;1780) =2S; G>2GeV to be found Why 1440 so big in psi radiative? pi_1(1600) in rho pi OK; similar width to b1pi;f1pi Hybrid character OK BUT… pi_1(1400): what is it? How many 1-+; Resonant? S-wave threshold effects; molecules... Pi(1850): hybrid? K*K*? More than one?? 1-+ Eugenio Pwa ambiguities affect output. What/which are the real resonance states? Then consider what they are Pennington

  2. Arndt Buccella Carlson Dyakanov Ellis Faber Giannini Huang Inoue Jaffe Karliner Lipkin Maltman Nussinov Oh Polyakov Qiang Rosner Stech Trilling U Veneziano Wilczek Xiang Yang Zhu If Theta doesn’t exist, then these (and many other theorists) should be congratulated on their creativity

  3. Include zero sigma expts (many): start with those and then compare the claimed signals = psychological different conclusion FC Less optimistic Don’t fall into creationism trap: “if you cant explain then it proves I am right”…. Null result that is “not inconsistent” with a signal is NOT support for the signal. HERA Ksp if real could be conventional Sigma; is NOT support for Theta_5 When appealing to models take account of ALL their implications e.g. of Sigma_5 narrow that should also be produced.

  4. New Heavy Mesons Lou; Maiani; Close

  5. ??? e+e- to + X Belle

  6. Inconsistent strengths? Belle and1+ ? radial ?? thresholds big ?

  7. Claim of Hybrid Charmonium by BELLE Is this the same as X(3940)? Is it hybrid charmonium as claimed? (See if is in psi rho as well)

  8. New Heavy Mesons Lou; Maiani; Close

  9. e+e- \to psi pi pi BaBar sees new vector cc* Y(4260)

  10. BaBar B decay to Y(4260)

  11. Y(4260) Three Possibilities Maiani Close Y(4260) = Non resonant S-wave threshold Close Lou Probably not………….

  12. Is it really a resonance? e+e- DD_1 is first S-wave charm threshold and occurs \sim 4.2 GeV ! psi D D_1 uu * pi pi e+e- Ds Ds_1 psi KK should show similar Lou

  13. f0(980)? Maybe; Confirm.

  14. All consistent with predictions for hybrid charmonium FC+Page 1995

  15. This is a clear distinction with hybrid for which this is ~ zero

  16. Maiani Close Psi polarisation test HQ symmetry would imply no psi; but also no 4260 For m_c DD_1 threshold and below D*D_0

  17. Y(4260) Two Possibilities Maiani Close DD_1 and not DsDs for hybrid DsDs and not DD_1 for tetraquark Experiment can decide
