Abstract
We calculate the double spin asymmetry of the diffractive 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 A_{ll} asymmetry. The A_{lT} asymmetry might be an appropriate object for this investigation.
