It is shown that the recent HERMES data on the transverse $Lambda^0$ polarization in the inclusive quasi-real photoproduction at $x_F>0$ can be accommodated by the strange quark scattering model. Relations with the quark recombination approach are discussed.
The total cross sections of the pp -> pK+ Lambda reaction near threshold measured at the COSY(Juelich) synchrotron using the internal target facility COSY-11 are described in the frame of the model taking into account the one pion and one kaon exchan
ge as well as the final state interaction mechanisms.
Transverse polarization of $Lambda^0$ hyperons in inclusive photoproduction at x_F>0 is tackled within the framework of the quark recombination model, which has been successfully applied to the polarization of different hyperons in a variety of unpol
arized hadron-hadron reactions. The results are compared with recent experimental data of HERMES.
