$${{\rho }}$$ ρ exchange contribution to neutrinoless double beta decay
Abstract We consider $$\rho $$ ρ meson contributions to neutrinoless double beta decay amplitude stemming from the hadronization of the short distance quark-electron currents. These contributions are evaluated within vacuum dominance approximation. The one and two $$\rho $$ ρ exchange contributions...
