Neutral Weak Current TwoBody Contributions in Inclusive Scattering from C12
Abstract
An ab initio calculation of the sum rules of the neutral weak response functions in C12 is reported, based on a realistic Hamiltonian, including two and threenucleon potentials, and on realistic currents, consisting of one and twobody terms. We find that the sum rules of the response functions associated with the longitudinal and transverse components of the (spacelike) neutral current are largest and that a significant portion (≃30%) of the calculated strength is due to twobody terms. This fact may have implications for the MiniBooNE and other neutrino quasielastic scattering data on nuclei.
