Polarized and transversity GPDs in kaon leptoproduction
  We study the kaon leptoproduction on the basis of the handbag approach. We consider the leading-twist contribution together with the transversity twist-3 effects which were found to be important in the description of pseudo-scalar meson production. We present our predictions for the cross section and spin asymmetries in the kaon leptoproduction.
