Researchers have precisely determined the worst-case tail probability for random variables with bounded kurtosis. The study identifies four distinct regimes governing these probabilities, with a specific four-regime map detailing the behavior based on threshold values and kurtosis constraints. This work refines existing bounds and provides explicit dual certificates and extremal distributions, with an AI-guided search aiding in the discovery of these precise mathematical relationships. AI
