  The discovery of the Higgs boson with a mass of about 125 GeV intimates us a
possibility of a high-scale supersymmetry (SUSY) breaking model, where a
sfermion mass scale is much higher than the electroweak scale. Although a
general SUSY standard model can contribute to the low-energy flavor and/or
CP-violating processes, the high-scale SUSY breaking model provides smaller
signatures and therefore are less constrained, even in the presence of large
flavor/CP violations of sfermions. However, a manner of gluino decay directly
reflects the squark flavor structure and provides us a clue for the sfermion
flavor structure. In this paper, we study the gluino decay in detail and
discuss the interplay with the gluino decay and low-energy flavor and CP
observation.
