| Summary:
Supersymmetry beyond the TeV scale offers several theoretical and
phenomenological advantages, such as accommodating the observed Higgs mass and
alleviating the flavor and CP problems. However, flavor and CP observables
still impose stringent constraints even at the PeV scale, motivating a
systematic study of flavor symmetries in this regime. In this work, we
investigate nucleon decay induced by dimension-five operators in supersymmetric
standard models and examine how flavor symmetries, particularly of the
Froggatt-Nielsen type, can suppress these operators. We perform a Bayesian
analysis combining flavor, CP, and proton-decay observables to quantify the
allowed parameter space and identify characteristic predictions. Our results
demonstrate that a multi-messenger approach, integrating flavor, CP, and
baryon-number-violating observables, is essential for probing the underlying
structure of supersymmetry beyond the TeV scale.
