Flipping SU(5) out of trouble

Minimal supersymmetric SU(5) GUTs are being squeezed by the recent values of αs, sin2θW, the lower limit on the lifetime for p→ν̄K decay, and other experimental data. We show how the minimal flipped SU(5) GUT survives these perils, accommodating the experimental values of αs and sin2θW and other constraints, while yielding a p→e/μ+π0 lifetime beyond the present experimental limit but potentially accessible to a further round of experiments. We exemplify our analysis using a set of benchmark supersymmetric scenarios proposed recently in a constrained MSSM framework.
