3. K-pp : basic building blockTest of Kbar nuclear physics • Predicted 2002 TY and Y. Akaishi, PLB 535 (2002) 70 BK = 48 MeV  = 61 MeV strange di-baryon, Kbar cluster, kaonic nuclear hydrogen molecule • Natural extension of K-p as (1405) K-pp, K-ppn, , based on the Akaishi-Y Kbar-N Interactions PRC 65 (2002) 044005

4. Starting ansatz:(1405) as “K-p atom” * decay channel Minv()* formation channel K- + p 27 MeV below threshold: not possible However, one can tune K- + “p” in nuclei resonates in emulsion, in 4He (* dominant)but not in d More evidence will be obtained (AMADEUS)

5. K- stopped in emulsion

7. Akaishi’s ATMS variational method: withelementary KN and NN interactions

8. K-p (*) “atom” persists in K-pp ! --> molecule

9. Heitler-London (1927) for H-H Heisenberg (1932) for p-nHe atom vs H2 molecule

10. Validity test onb, KN-hardcore, NN-hardcore Starting ansatz (1405) --> robustly predicted K-pp

11. ATMS prediction for Kpp quite robust:consistent withN.V. Shevchenko, A. Gal and J. Mares, arXiv:nucl-th/0610022.Y. Ikeda and T. Sato, HYP2006 contribution. Kpp beyond the present approach Validity of the (1405) Ansatz Unknown interactions pertinent to 3-body systems; p-wave, , , KN interaction modified by chiral symmetry restoration, quark structure, , , NN barrier weakened by Kbar ?

12. a la K. Nishijima Yukawa’s strugglingin 1933how can such a migrating real particle exist in nuclei?Bose electron ?force range ? p + e- = n ? Finally, in 1935, Yukawa arrived at virtual mediatingparticle

13. The Yukawa theory A virtual particle mediates strong interaction • mU/me ~ 200 • The mesons discovered • Fundamental concept in physics Heitler-London- Heisenberg scheme: completely abandoned ?

16. Nuclear density = constant Universal law ? Why ? saturation Common nuclear force A different N-N interaction would produce a different nuclear density --> different matter world Super Strong Nuclear Force

17. Range and Coherency of Kbar bonding Yukawa coupling (virtual meson) range: short ~ 1/mB saturation, constant nuclear density Kbar covalency (real Kbar: anti-u,d) large exchange energy range: short - medium: ~ 1/BK ~ 1405 size higher density, large coherency range Kpp Kppp Kpppp Akaishi, Dote KKpp KKppp Akaishi, Dote

18. migrating-K- coherency length Maybe ~5 (Dote) With increasing K-

19. K-condensed matter:matter by coherently migrating K- High density Liquid, Solid?

20. Molecular structure revealedjustifies(1405) as an atom doorway: seed doorway: successive seed * formation and propagation K- absorption: old evidence p-p reaction: predicted, prepared

21. K-pp formation How to prove the high density in Kbar nuclei ? p + p --> K+ + p + * *p sticking --> K+ + K-pp:K-pp -->  + p

22. Conventional reactions: small sticking

23. Extraordinary sticking of * + p into K-pp ** short collision length of pp ** compactness of K-pp ** large momentum transfer

24. Predicted spectra
