Flavor of gluino decay in high-scale supersymmetry

  • Ryosuke Sato

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.
