Diquarks in heavy baryonsAtsushi Hosaka (RCNP, Osaka U. )

Practical questions of hadron physics• How ground and excited states are described?• Are there simple language for it when quarks and gluons interact strongly• Are there kinds of quasi-particles interacting weakly
• Constituent quarks: Mere useful tool of symmetry realization or Dynamically realistic and active object• How can diquarks be be identified in multi-quark systems Baryons, nuclei, nuclear matter, quark matter
• ee has repulsive force, BUT• qq has attractive force SU(3)c : half of qqbar attraction SU(2)c : Same as qqbar Pauli-Gursey symmetry ~ several hundred MeV
• Diquark can be seen better in heavy baryons than in light
