Polarized and unpolarized off-shell $H^{\ast }\to ZZ\to 4\ell$ decay above the $2m_Z$ threshold

A. I. Hernández-Juárez, R. Gaitán, G. Tavares-Velasco

An analysis of the off-shell $H^{\ast }\to ZZ\to {\overline{\ell }}_1{\ell }_1{\overline{\ell }}_2{\ell }_2$ decay width is presented for both unpolarized and polarized $Z$ gauge…
