Lightest Higgs decay to a charm quark pair in the MSSM at full one loop level with flavour violation

We study lightest neutral Higgs decay to a pair of charm quarks in the MSSM at full one-loop level with non-minimal quark flavour violation (QFV). The process is renormalised in the \bar{DR} scheme. In the numerical analysis we consider mixing between the second and the third squark generations and the relevantconstraints from B meson data are taken into account. It is shown that the full one-loop corrected decay width can be quite sensitive to the MSSM QFV parameters and can differ up to ~ 60% from its SM value, due to large scharm-stop mixing and large QFV/QFC trilinear couplings. After summarising the theoretical and experimental errors we conclude that an observation of these SUSY QFV effects is possible with a good chance at the ILC.
