Deuteron Breakup pd\to pnp in Specific Kinematics and Short-Range NN-Interaction
Abstract
Deuteron breakup processes $p+d\to (NN)_{s,t}+N$ are studied in the kinematics of backward elastic pd-scattering at law relative momenta of the NN-pair $k\sim 0-50 MeV/c$ for initial energies $T_0=0.5-2.5 GeV$ in the framework of the known mechanisms of the $pd\to dp$ process including rescatterings in the initial and final states. A considerable suppression of the $Δ-$ and $N^*-$ isobar excitation mechanisms is found for the production of the singlet $(NN)_s$-pair. As a result, one nucleon exchange mechanism can be identified in the cross section and polarization observables by the node of the half-off-shell NN$(~^1S_0)$-scattering amplitude, $t(q,k)$, at $q\sim 0.4 $ GeV/c.
