abstract = {We study the loop-induced decays h0 → γγ and h0 → gg in  the Minimal Supersymmetric Standard Model (MSSM) with quark  flavor violation (QFV), identifying h0 with the Higgs boson  with a mass of 125 GeV, where γ and g are photon and gluon,  respectively. We perform a MSSM parameter scan and a detailed  analysis around a fixed reference point respecting theoretical  constraints from vacuum stability conditions and experimental  constraints, such as those from B-meson data and electroweak  precision data, as well as recent limits on Supersymmetric  (SUSY) particle masses from LHC experiments. We find that  (i) the relative deviation of the decay width Γ(h0 → gg) from  the Standard Model value, DEV(g), can be large and negative,  ≲−15%,  (ii) the analogous deviation of Γ(h0 → γγ) is strongly  correlated, DEV(γ) ≃−1/4DEV(g) for DEV(g) ≲−4%,  (iii) the relative deviation of the width ratio  Γ(h0 → γγ)/Γ(h0 → gg) from the SM value, DEV(γ/g),  can be large (up to ∼20%),  (iv) the deviations can be large due to the up-type squark  loop contributions,  (v) the SUSY QFV parameters can have a significant effect  on these deviations. Such large deviations can be observed  at a future e+e− collider like ILC.  Observation of the deviation patterns as shown in this study  would favor the MSSM with flavor-violating squark mixings and  encourage to perform further studies in this model.},
