| contents | We consider the rare decay channels of the $Z$ boson: $Z \to \text{two}\ \textrm{jets} + γ$ and $Z \to \text{two}\ \textrm{jets} +2\, γ$. To obtain the widths and distributions for these processes, we compute the effect of NLO QCD corrections to the processes $Z \to q {\bar q}+ γ$ and $Z \to q {\bar q} +2\, γ$. We find that these corrections reduce the widths of these processes by about $6.03\%$ and $12.39\%$, respectively. The reduction in the partial widths is larger at the jet level. These NLO-improved decay observables may be tested in future runs of the LHC or at future $e^{+}e^{-}$ colliders. |
