Description
A theoretical analysis of the $C\!$-conserving semileptonic decays $\eta^{(\prime)}\to \pi^0 l^+ l^-$ and $\eta^{\prime}\to \eta l^+ l^-$ ($l=e$ or $\mu$) is carried out within the framework of the Vector Meson Dominance (VMD) model. A phenomenological model is used to parametrise the VMD coupling constants and the associated numerical values are obtained from an optimisation fit to $V\to P\gamma$ and $P\to V\gamma$ radiative decays ($V=\rho^0,\omega,\phi$ and $P=\pi^0,\eta,\eta^\prime$). Finally, the signature of $C\!P$ violating operators from the SMEFT on experimental observables is investigated and quantified for the $l=\mu$ case.
