Generalized Contact Formalism Analysis of the ${}^4$He$(e,e^{\prime }pN)$ Reaction

Abstract

Measurements of short-range correlations in exclusive ${}^4$He$(e,e^{\prime }pN)$ reactions are analyzed using the Generalized Contact Formalism (GCF). We consider both instant-form and light-cone formulations with both the AV18 and local N2LO(1.0) nucleon-nucleon ($NN$) potentials. We find that kinematic distributions, such as the reconstructed pair opening angle, recoil neutron momentum distribution, and pair center of mass motion, as well as the measured missing energy, missing mass distributions, are all well reproduced by GCF calculations. The missing momentum dependence of the measured ${}^4$He$(e,e^{\prime }pN)$ / ${}^4$He$(e,e^{\prime }p)$ cross-section ratios, sensitive to nature of the $NN$ interaction at short-distacnes, are also well reproduced by GCF calculations using either interaction and formulation. This gives credence to the GCF scale-separated factorized description of the short-distance many-body nuclear wave-function.
