Description: This paper explores Ultra-Slow-Roll Inflation using composite boson models. The research finds a parameter space yielding 55 to 60 e-folds of inflation and predicts extremely light primordial black holes (10–100,5 grams). These PBHs require the memory-burden effect to survive as dark matter, though their gravitational wave signals are currently beyond the reach of existing detectors.
