Abstract: (Springer)

The cross section of isolated nucleon production with large transverse momentum in nucleonnucleon collisions is calculated. This process is due to the hard scatteringqq→B q. A general selection rule for helicity amplitudes of the processes involving mesons and baryons is established. In particular it leads to the vanishing of the amplitudesq+q+

\to B_{ + 3/2} \bar q - ; \gamma _ +\gamma _ +\to M_{ + 1} M_{ - 1} ,B_{ + 3/2} \bar B_{ - 3/2}

. The quantitative estimates using the nucleon wave function from [5] show that the selection of the events with isolated proton production is possible in ISR data.
