  Single-spin asymmetry appears due to the interference of single and double
gluon exchange between protons. A heavy fermion model is used to describe the
jet production in the interaction of gluon with the proton implying the further
averaging over its mass. As usually in one-spin correlations, the imaginary
part of the double gluon exchange amplitude play the relevant role. The
asymmetry in the inclusive set-up with the pion tagged in the fragmentation
region of the polarized proton does not depend on the center of mass energy in
the limits of its large values. The lowest order radiative corrections to the
polarized and unpolarized contributions to the differential cross sections are
calculated in the leading logarithmical approximation. In general, a
coefficient at logarithm of the ratio of cms energy to the pion mass depends on
transversal momentum of the pion. This ratio of the lowest order contribution
to the asymmetry may be interpreted as the partial contribution to the odderon
intercept. The ratio of the relevant contributions in the unpolarized case can
be associated with the partial contribution to the pomeron intercept. The
numerical results given for the model describe the jet as a heavy fermion decay
fragments.
