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.
