Angular and invariant-mass observables in the four-body Higgs decay $h\to \ell {\bar{\nu }}_{\ell }{\bar{\ell }}^{\prime }{\nu }_{{\ell }^{\prime }}$

Han Zhang, Bai-Cian Ke, Yao Yu +2

We study the angular distribution of the Higgs boson decay $h\to \ell {\bar{\nu }}_{\ell }{\bar{\ell }}^{\prime }{\nu }_{{\ell }^{\prime }}$ with $\ell \ne {\ell }^{\prime }$. Due to the presence of two undetected ne…
