  1. Could there be a more direct proof of multiquark configuration? • Measure v2 in heavy ion collisions

  2. “4 quarks”

  3. Through p+ p- or K+ K- Future heavy ion can look at v2 of the following Scalar nonet X(3872): J/y p+ p– Z(4430): y‘ p+ Z1,Z2 : cc1p+

  4. Could there be a more direct proof of multiqurk configuration? • Measure Tcc at Belle •  ? 3800 MeV explicitly exotic • Z. Zouzou, B. Silverstre-Brac, C. Gilgnooux, J Richard (86), D. Janc, M. Rosina (04), Y. Cui, S. L. Zhu (07) • QCD sum rules: F Navarra, M.Nielsen, SHLee, PLB 649, 166 (2007) • simple quark model: SHL, S. Yasui, W.Liu, C Ko EPJ C54, 259 (2008)

  5. For doubly charmed tetraquark c c = -143 MeV xmc2 For the D and D* meson c c = -64 MeV xmc xmc Why 1+ (Tcc) For a Tetraquark s u s d For the K and K* meson u d s s

  6. Can also look for 1+ (Tcc) c e c Tcc (3800) c c e+ SHL, S Yasui, W Liu, Cko (08) Belle: PRL 98, 082001 (07) e+ e-  J/y + X(3904)  D D*
