$\Gamma_{9}$ ${{\mathit t}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit q}}$ (${{\mathit q}}={{\mathit u}},{{\mathit c}}$) $<5 \times 10^{-4}$ CL= 95%
Category: $\Delta \mathit T$ = 1 weak neutral current ($\mathit T1$) modes
Note: (T1) Allowed by higher-order electroweak interactions.
Note: This limit is for $\Gamma\mathrm {( {{\mathit t}} \rightarrow {{\mathit Z}} {{\mathit q}} )}/\Gamma\mathrm {( {{\mathit t}} \rightarrow {{\mathit W}} {{\mathit b}} )}$.
The following data is related to the above value:
$\Gamma($ ${{\mathit t}}$ $\rightarrow$ ${{\mathit Z}}{{\mathit q}}$ (${{\mathit q}}={{\mathit u}},{{\mathit c}}))/\Gamma_{\text{total}}$
$\Gamma_{9}/\Gamma$
