Query: Diffractive Contribution to $A_\perp$ asymmetry   We consider double spin asymmetries for longitudinally polarized leptons and
transversally polarized protons in diffractive vector meson and $Q \bar Q$
production at high energy range on the basis of two-gluon model. The asymmetry
predicted for meson production is quite small. Large asymmetry is expected for
$Q \bar Q$ production.
