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 A_ll asymmetry. The A_lT asymmetry might be an appropriate object for this investigation.
