2026-06-18 (Branch B decided: the explicit PS threshold model [formula in source] proton-decay window — minimal content killed, [formula in source] survives, Hyper-K decisive, v266)
Research changelog · TFPT — Introduction and reading guide
v266_ps_threshold_proton.py ( PS.PROTON.02/ PS.THRESHOLD.02) decides branch B of the v265 fork. The explicit two-step Pati–Salam thresholds give [formula in source] [formula in source] (writes ps_threshold_proton.json): \ the minimal [formula in source] -Higgs content ( [formula in source] ) gives [formula in source] yr [formula in source] Super-K and is killed even at the high hadronic band; \ the [formula in source
