Title: 12C(e,e'pN) measurements of short range correlations in the tensor-to-scalar interaction transition region

Abstract

High-momentum configurations of nucleon pairs at short-distance are probed using measurements of the $$^{12}$$C$$(e,e'p)$ and $$^{12}$$C$$(e,e'pN)$ reactions (where $$N$$ is either $$n$$ or $$p$$), at high-$Q^2$ and $$x_B>1.1$$. The data span a missing-momentum range of 300--1000 MeV/c and are predominantly sensitive to the transition region of the strong nuclear interaction from a Tensor to Scalar interaction. The data are well reproduced by theoretical calculations using the Generalized Contact Formalism with both chiral and phenomenological nucleon-nucleon ($NN$) interaction models. This agreement suggests that the measured high missing-momentum protons up to $1000$ MeV/c predominantly belong to short-ranged correlated (SRC) pairs. The measured $$^{12}$$C$$(e,e'pN)$ / $$^{12}$$C$$(e,e'p)$ and $$^{12}$$C$$(e,e'pp)$ / $$^{12}$$C$$(e,e'pn)$ cross-section ratios are consistent with a decrease in the fraction of proton-neutron SRC pairs and increase in the fraction of proton-proton SRC pairs with increasing missing momentum. This confirms the transition from an isospin-dependent tensor $NN$ interaction at $$\sim 400$$ MeV/c to an isospin-independent scalar interaction at high-momentum around $$\sim 800$$ MeV/c as predicted by theoretical calculation.
