VII. Few-body research community

• astrophysics
• particle, nuclear - FB - atomic, condensed
  matter
• chemistry, biomed
• FB conferences every 2-3 years since 1967
• European FB since 1975, Asian-Pacific since 1999
• (typically 200-400 participants from 20 40
  countries)
• FewBody Systems 1986 (W. Plessas)
• APS FB 330 vs APS NP 2476

39
VIII CHALLENGES

• Nuclear interaction at N3LO (with 3NF) even N4LO
  implying CD and CSB
• More EFT ?PT studies required
• Rigorous 3B, 4B, GFMC, NCSM using NnLO with n 3
  and CD CSB
• Relativity
• Short range dibaryon Moscow/Tübingen p-e EFT
  potentials should give the same result for all
  observables
• Can all EFT parameters be uniquel determined?
• Latitude in fine tuning PS and parameters?

40

• 8) p-N scattering data should get pNN cc
• 9) Several potentials - temporary
• 10) N hyperon and H H interaction
• 11) Mesons, baryons, resonances hybrids,
  glueballs, etc topics of conferences NSTAR,
  MENU, ETAMESON, e.g.
• np?d? relativistic descriptions
• and PWA workshops, eg Abilene, Zagreb,
  Tuzla
• 12) Symmetries

41
13) FB systems ideal for new physics search
- weak charge of p (Jlab) - KN
scatt. length to test ?SB in systems with
strangenness using DEAR and SIDDHARTA 14)
New facilities Bernal Polanyi polemics 15)
Discrepancies solved using proper 3NF
or ? However, there are other discrepancies 16)
Therefore, several approaches desirable 17)
Rennaisance of nuclear physics 3B actually
