Özet

In this work, we analyze c --> u gamma decay in supersymmetry for a light sbottom with heavy scalar fermions of the first two generations. Assuming that all generation changing entries of the sfermion mass matrices vanish and, thus considering only chargino, charged Higgs and W-boson contributions only, we calculate the Wilson coefficients and the decay rate at mu = m(c) level. It is found that, for low tan beta regime the decay rate is enhanced up to 5% with respect to the SM. The results presented here are expected to be checked in the CHORUS experiment in the near future.
