Semi-invisible hyperon decays in the effective Lagrangian approach

Abstract We systematically investigate the semi-invisible decays of hyperons (hyperon $$\rightarrow \pi (/\gamma )\ +$$ → π ( / γ ) + invisible( $$\psi $$ ψ )) in the Mesogenesis mechanism by the effective Lagrangian approach. The one-loop hadronic contribution of triangle diagra...
