Description
We compute the decay width of $h^0 \to c \bar{c}$ in the MSSM with quark flavor
violation (QFV) at full one-loop level in the $\overline{\rm DR}$
renormalization scheme. We study the effects of $\tilde{c}-\tilde{t}$ mixing,
taking into account the constraints on QFV from the B meson data. We find that
the full one-loop corrected decay width $\Gamma(h^0 \to c \bar{c})$ is very
sensitive to the MSSM QFV parameters.
In a scenario with large $\tilde{c}-\tilde{t}$ mixing,
$\Gamma(h^0 \to c \bar{c})$ can differ up to $\sim \pm 35\%$ from its SM value. After estimating the uncertainties of the width, we conclude that an observation
of these QFV SUSY effects is possible at a future $e^+ e^-$ collider such as ILC.
