Spin Effects in Diffractive Q Q Production and Compass Experiment
Abstract
We calculate the double spin asymmetry of the diffractive Q Q and vector meson leptoproduction at COMPASS energies. We analyze dependences of the asymmetry on the structure of the Pomeron-proton coupling. It is shown that it is difficult to study the spin structure of the Pomeron coupling with the proton from the All asymmetry. The AlT asymmetry might be an appropriate object for this investigation.
