Diffractive S and D-wave vector mesons in deep inelastic scattering
Abstract
We derive helicity amplitudes for diffractive leptoproduction of the S and D wave states of vector mesons. We predict a dramatically different spin dependence for production of the S and D wave vector mesons. We find very small $R=σ_{L}/σ_{T}$ and abnormally large higher twist effects in production of longitudinally polarized D-wave vector mesons.
