Predictions are elaborated for nucleon decay in supersymmetric grand unified theories (SUSY GUT's). A minimal SU/sub 5/ SUSY GUT is described, as well as SU/sub 5/ breaking. The low energy theory and breaking of supersymmetry are discussed. It is concluded that nucleon decay in SUSY GUT's would be dominated by p ..-->.. K/sup +/anti nu/sub ..mu../ and n ..-->.. K/sup 0/anti nu/sub ..mu../. There are ranges in parameter space for which other decay modes may be significant or may even dominate, it is found. It is noted that minimal SUSY GUT's typically predict a value of sin/sup 2/theta/sub w/ of order .233. 20 refs., 7 figs. (LEW)
