Abstract

The exclusive reaction 12C(p, ppN)10A of quasi-elastic knockout of the nucleon from the short-rangecorrelated nucleon pair <NN> in the 12C nucleus by proton with an energy of few GeV is considered in the plane-wave approximation.The two-nucleon spectroscopic factors and momentum distributions of the center of mass motion of NN-pairs are considered by analogy with theory of quasi-elastic knockout of fast deuteron clusters from nuclei (p, Nd) using the translationally-invariant shell model.

Highlights

Quasi-elastic knock-out of fast deuterons from 12C nucleus by protons at 670 MeV discovered in Dubna in 1957 [1] had demonstrated surprisingly high cross section
It is important to get together with the results of the short-range correlations (SRC) experiment [7] some data at the same beam energy on the reaction of quasi-elastic knockout of the fast deuterons 12C(p, pd)10B at high transferred momenta corresponding to the p→ pd scattering at ≈ 90◦ in the center mass of the pd system
The exclusive reaction 12C(p, ppN)10A of quasi-elastic knockout of the nucleon from the short-range correlated nucleon pair in the 12C nucleus by proton with an energy of few GeV is considered in the plane-wave impulse approximation by analogy with theory of reactions of quasi-elastic knockout of fast deuterons (p, pd)

Summary

Introduction

Quasi-elastic knock-out of fast deuterons from 12C nucleus by protons at 670 MeV discovered in Dubna in 1957 [1] had demonstrated surprisingly high cross section. A new experiment for study of the SRC in the 12C nucleus was performed at the BM@N in JINR [7] and analysis of the collected data is in progress In this experiment an inverse kinematics is used, where the 12C beam with momentum 4 GeV/c per nucleon interacts with the liquid hydrogen target providing the transition 12C + p → pp + N + 10A. Since the internal momentum qrel in the SRC pair is large, the relativistic effects are necessary to take into account. These effects are considered in [8] within the light-front dynamics.
