  ABSTRACT: This paper investigates the decay properties of solutions to the Cauchy problem for viscoelastic nonlinear hyperbolic dissipative systems on ℝ 3 . Due to the weak dissipation of the system, the decay estimate of solutions exhibits a loss of regularity, implying that a higher regularity of initial data is required for optimal decay rates compared to the global existence. The aim is to reduce the initial regularity to the lowest possible level to achieve the optimal decay rate. Based on the global existence, we employ energy methods, L p - L q - L r estimates, and harmonic analysis tools to obtain the optimal decay result of solutions.
