Abstract

We compute the decay width of h⁰\ensuremath→cc 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 \stackrel\texttildelowc\ensuremath-\stackrel\texttildelowt mixing, taking into account the constraints from the B meson data. We show that the full one-loop corrected decay width \mathrm\ensuremathΓ(h⁰\ensuremath→cc) is very sensitive to the minimal supersymmetric Standard Model QFV parameters. In a scenario with large \stackrel\texttildelowc_L,R\ensuremath-\stackrel\texttildelowt_L,R mixing \mathrm\ensuremathΓ(h⁰\ensuremath→cc) can differ up to \ensuremath∼\ifmmode±\else\textpm\fi35% 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^\ensuremath- collider (International Linear Collider).
