$\Gamma_{184}$ ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \phi}}$ , ${{\mathit \phi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ ($1.8$ $\pm0.8$) $ \times 10^{-6}$
Category: $\Delta \mathit C$ = 1 weak neutral current ($\mathit C1$) modes, or Lepton Family number ($\mathit LF$) , or Lepton number ($\mathit L$), or Baryon number (B) violating modes
Note: This is $\mathit not$ a test for the $\Delta \mathit C$=1 weak neutral current, but leads to the ${{\mathit \pi}^{+}}{{\mathit \ell}^{+}}{{\mathit \ell}^{-}}$ final state.
The following data is related to the above value:
$\Gamma($ ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \phi}}$ , ${{\mathit \phi}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}})/\Gamma_{\text{total}}$
