Abstract
We calculate the decay width of h0→bb¯¯ in the Minimal Supersymmetric Standard Model (MSSM) with quark flavour violation (QFV) at full one-loop level. We study the effect of c~−t~ mixing and s~−b~ mixing taking into account the constraints from the B meson data. We discuss and compare in detail the decays h0→cc¯¯ and h0→bb¯¯ within the framework of the perturbative mass insertion technique using the Flavour Expansion Theorem. The deviation of both decay widths from the Standard Model values can be quite large. Whereas in h0→cc¯¯ it is almost entirely due to the flavour violating part of the MSSM, in h0→bb¯¯ it is mainly due to the flavour conserving part. Nevertheless, the QFV contribution to Γ(h0→bb¯¯) due to c~−t~ mixing and chargino exchange can go up to ∼ 7%.
