VECTOR MESONS
  • r , w , f , Y , U
  • VIRTUAL PHOTON
  • g(Q2)
  • PROTON
  • p

6
Polarizations T , L
  • Wave functions
  • Photons and vector mesons Quark-antiquark
    systems
  • Proton quark-diquark

7
Vector mesons BL and BSW
wfOverlapsltphoton dipole(r)
VMgtdipole-proton interactionIntegrate over
all dipolesthat form the wave functions
8
Mechanisms for the dipole-dipole
interactionPomerons, QCD vacuum
correlations, two-gluon exchanges Perturbative
Vs NonperturbativeUnique calculations? Free
parameters? Unified description of all vector
