- Abstract
We compute the decay width of h(0) -> c (c) over bar in the minimal supersymmetric Standard Model with quark flavor violation (QFV) at full one-loop level adopting the DR renormalization scheme. We study the effects of (c) over tilde - (t) over tilde mixing, taking into account the constraints from the B meson data. We show that the full one-loop corrected decay width Gamma(h(0) -> c (c) over bar) is very sensitive to the minimal supersymmetric Standard Model QFV parameters. In a scenario with large (c) over tilde (L,R) - (t) over tilde (L,R) mixing Gamma(h(0) -> c (c) over bar) can differ up to similar to +/- 35% from its Standard Model value. After estimating the uncertainties of the width, we conclude that an observation of these supersymmetry QFV effects is possible at an e(+)e(-) collider (International Linear Collider).
