Electromagnetic response of 12C: a first-principles calculation

Nuclear Theory 2016-08-24 v1 High Energy Physics - Experiment

Abstract

The longitudinal and transverse electromagnetic response functions of 12^{12}C are computed in a "first-principles" Green's function Monte Carlo calculation, based on realistic two- and three-nucleon interactions and associated one- and two-body currents. We find excellent agreement between theory and experiment and, in particular, no evidence for the quenching of measured versus calculated longitudinal response. This is further corroborated by a re-analysis of the Coulomb sum rule, in which the contributions from the low-lying JπJ^\pi\,=2+\, 2^+, 02+0^+_2 (Hoyle), and 4+4^+ states in 12^{12}C are accounted for explicitly in evaluating the total inelastic strength.
