This conclusion is inconsistent with the idea of Vector Meson Dominance (VMD).
The idea of Vector Meson Dominance is inconsistent with Wigner's analysis of the irreducible representations of the Poincare group.
The experimental plan involves a series of measurements in two and few nucleon systems (to minimize nuclear structure effects) to determine the weak-interaction amplitudes either in the vector meson exchange model or expressed as a function of transition amplitudes between S-wave and P-wave states.
The reader won't come out knowing all there is to know about the partial width of the cross section of semileptonic vector meson decay, but he will get enough to satisfy his curiosity, while keeping his attention.
Papers are presented grouped into the main topics of structure function, vector mesons, electroweak and beyond the standard model, hadronic final states, heavy flavors, spin physics, and the future of DIS.
