摘要：

We investigate manifestations of SUSY in rare B-meson decays Bd→Kφ0, K+π- which proceed mainly via penguin diagrams. It is shown that there exists a range of masses of SUSY particles where the SUSY contribution to the amplitudes of the processes exceeds the standard one. We obtain constraints on SUSY particle masses which may be competitive with the accelerator ones. © 1990.
