Abstract
We make use of the topological chiral soliton model of the nucleon to predict the form factors related to the parity-violating meson-nucleon vertices. We find that these are of monopole type at low q 2 with cut-offs similar to the equivalent strong meson-nucleon form factors. We furthermore investigate the parity-violating πΔN vertex. We find that while the isoscalar coupling vanishes identically, the isovector parity-violating πΔN vertex has a coupling stant of about 2 × 10 −8 being of comparable magnitude as the equivalent weak pion-nucleon vertex strength. We also discuss the parity-violating ωΔN and ρΔN vertices in the model and furthermore comment on the pv meson ΔΔ vertices. In the appendix we will correct the formula for h ω 0 of ref. 5), where some terms have been omitted.
