The proton-proton parity-violating longitudinal asymmetry is calculated in the lab-energy range 0-350 MeV, using a number of different, latest-generation strong-interaction potentials-Argonne v 18 , Bonn-2000, and Nijmegen-I-in combination with a weak-interaction potential consisting of ρ-and ω-meson exchanges-the model known as DDH. The complete scattering problem in the presence of parity-conserving, including Coulomb, and parity-violating potentials is solved in both configuration-and momentum-space. The predicted parity-violating asymmetries are found to be only weakly dependent upon the input strong-interaction potential adopted in the calculation. Values for the ρ-and ω-meson weak coupling constants h pp ρ and h pp ω are determined by reproducing the measured asymmetries at 13.6 MeV, 45 MeV, and 221 MeV. 21.30.+y, 25.40.Cm
The structure of the three-body nnΛ system, which has been observed recently by the HypHI collaboration, is investigated taking ΛN − ΣN coupling explicitly into account. The Y N and N N interactions employed in this work reproduce the binding energies of
Ab-initio calculations of light nuclei require three-nucleon potentials in addition to realistic two-nucleon forces to obtain the empirical binding energies. The current status of the Illinois three-nucleon potentials used with Argonne vig is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
