| Publication Abstract: | The strong nuclear interaction is probed at short-distance and high-momenta using new measurements of the 12C(e,e'p) and 12C(e,e'pn) reactions, at high-Q2 and xB > 1. The data span a missing-momentum range of 300{850 MeV/c and is predominantly sensitive to the dominant proton-neutron short-range correlated (SRC) pairs and complements previous 12C(e,e'pp) measurements. 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, observed here for the ?rst time, suggests that the measured high missing-momentum protons up to 850 MeV/c belonged to SRC pairs. The measured 12C(e,e'pn) / 12C(e,e'p) ratio is consistent with a decrease in the fraction of proton-neutron SRC pairs with increasing missing-momentum. This confirms the transition from an isospin-dependent tensor NN interaction at ~ 400 MeV/c to an isospin-independent scalar interaction at high-momentum around ~ 800 MeV/c. |
