Distributions of some of the final-state observables sensitive to the spin and parity of the resonance in the $H\to Z{Z}^{\ast }\to 4\ell$ signal region $115\text{GeV}<m_{4\ell }<130\text{GeV}$ for data (points with errors), backgrounds (filled histograms) and predictions for two spin hypotheses (SM solid line and alternatives dashed lines). a–c Invariant masses $m_{12}$ , $m_{34}$ and decay $cos{\mathit{\theta }}_1$, respectively; d–f $\mathrm{\Phi }$, $cos{\mathit{\theta }}^{\ast }$ and ${\mathrm{\Phi }}_1$, respectively
