A Possibility to Observe Short-Range NN Properties in the Deuteron Breakup $pd\to ppn$

Abstract

Quasi-binary reaction of the deuteron breakup $p+d\to (pp)+n$ with the final proton-proton pair $(pp)$ in the ${}^1{S}_0$ state is analyzed at initial energies $0.5-2$ GeV in the kinematics of backward elastic pd-scattering $pd\to dp$. On the basis of the main mechanisms of the $pd\to dp$ process, including initial and final state interaction, we show that unpolarized cross section and spin observables of this reaction exhibit important properties of the half-off-shell $pp{(}^1{S}_0)$-scattering amplitude, which are relevant to the nucleon-nucleon interaction at short distances.
