چکیده انگلیسی
We calculate the decay width of h0âbbâ¾ in the Minimal Supersymmetric Standard Model (MSSM) with quark-flavour violation (QFV) at full one-loop level. The effect of cËâtË mixing and sËâbË mixing is studied taking into account the constraints from the B-meson data. We discuss and compare in detail the decays h0âccâ¾ and h0âbbâ¾ within the framework of the perturbative mass insertion technique using the Flavour Expansion Theorem. The deviation of both decay widths from the Standard Model results can be quite large. While in h0âccâ¾ it is almost entirely due to the flavour violating part of the MSSM, in h0âbbâ¾ it is mainly due to the flavour conserving part. Nevertheless, Î(h0âbbâ¾) can fluctuate up to â¼7% due to QFV chargino exchange with large cËâtË mixing.
