Home Works for Theorists

• So far works are done mainly for interpreting the
  observed phenomena. But, we need more predictions

Multiquarks
Tetraquark qq- qq-correlations, udud,
etc for s, ?, f0, a0, Ds, Molecular type,
?(1405), N(1535), Heavy baryon analogues?
Dynamical questions qq or qq correlations
-gt formation of diquarks in hadrons What is
appropriate picture of hadron excitations
quark excitation -gt single particle -gt quarkonia
qq creation -gt multiquakrs Mixing
of different seeds. Do the number of states
conserve? Do they change as functions of
flavors, density and temperature
How to? Spectroscopy, decays, productions,
fragmentation functions
Reaction dynamics
Effective Lagrangian method, tree level
Coupled channel dynamics-gt interference,
threshold effects Physical meaning of model
parameters, hadron loop, quark structure
8
Roles of symmetry
Spontaneous breaking of chiral symmetry
mass generation of light quarks, constituent
quarks Dynamics of pions Vector
mesons Gauge symmetry, Hidden gauge
symmetry Symmetry for heavy quark systems
change in spin-spin interactions
(non-perturbative?)
Make predictions and proposals for
experiments Work with Lattice for inputs of models
Find a reasonable effective model with
quasi-particles From simplicity to variety
