Abstract
A scaling hypothesis for the spectral density of excitations is proposed to account for the linear and power-law behavior observed in the quasiparticle scattering rate of high-temperature superconducting compounds. This proposal naturally explains the disappearance of superconductivity in compounds in which the scattering rate deviates from its characteristic linear behavior. The renormalization-group treatment of marginal-Fermi-liquid theory is seen to support the scaling hypothesis.
