ρ-ω mixing in nuclear charge asymmetry

Abstract
The particle physics input to the NN charge asymmetric potential due to ρ-ω mixing is updated. The calculated changes in scattering lengths ‖annapp1.3±0.2 fm are in good agreement with experiment (∼1.4±0.8 fm), as are the contributions to the binding energy difference in the A=3 mirror nuclei.
