Abstract
Phys.Rev. C70 (2004) 058201 In this paper scattering equivalences are used to simplify current operators
in constituent quark models. The simplicity of the method is illustrated by
applying it to a relativistic constituent quark model that fits the meson mass
spectrum. This model requires a non-trivial constituent quark current operator
to fit the pion form factor data. A model with a different confining
interaction, that has the identical spectrum and can reproduce the measured
pion form factor using only point-like constituent quark impulse currents is
constructed. Both the original and transformed models are relativistic
direct-interaction models with a light-front kinematic subgroup.
