We discuss entanglement and violation of Bell-type inequalities for a systemof two $Z$ bosons produced in Higgs decays. We take into account beyond theStandard Model (anomalous) coupling between $H$ and daughter bosons but welimit ourselves to an overall scalar $ZZ$ state (we exclude the possibilitythat $H$ contains a pseudo-scalar component). In particular we consider thecase when each $Z$ decays further into fermion-antifermion pair. We find that a$ZZ$ state is entangled and violates the CGLMP inequality for all values of the(anomalous) coupling constant.
