We investigate supercorrelated decay of an initially inverted ensemble of two-level emitters, where cooperative emission is governed by higher powers of the collective decay operator beyond conventional Dicke superradiance. We develop a qualitative theoretical framework that captures the essential mechanism of generalized supercorrelated decay and predicts the corresponding scaling laws. This framework clarifies the physical distinctions between conventional superradiance and higher-order supercorrelated emission. We further analyze the phenomenon in a waveguide quantum electrodynamics setting, where guided modes mediate strong collective interactions. By deriving an effective semiclassical theory, we obtain a computationally efficient description that enables large-scale simulations of the dynamics.
