Abstract
The gluino-induced contributions to the decay (Formula presented) are investigated in supersymmetric frameworks with generic sources of flavor violation. It is shown that, when QCD corrections are taken into account, the relevant operator basis of the standard model effective Hamiltonian gets enlarged to contain (i) magnetic and chromomagnetic operators with a factor of (Formula presented) and weighted by a quark mass (Formula presented) or (Formula presented) (ii) magnetic and chromomagnetic operators of lower dimensionality, also containing (Formula presented) and (iii) four-quark operators weighted by a factor (Formula presented) Numerical results are given, showing the effects of the leading order QCD corrections on the inclusive branching ratio for (Formula presented) Constraints on supersymmetric sources of flavor violation are derived.
