What Does CPST Stand For?

CPST stands for Classical Perturbation Scattering Theory

Classical Perturbation Scattering Theory (CPST) is a theoretical framework used to analyze the scattering of waves or particles when subjected to perturbations in their classical motion. It employs perturbative techniques to derive approximate solutions for the scattering amplitude and cross-sections, enabling the study of complex interactions in various physical systems. CPST is applicable in fields such as astrophysics, quantum mechanics, and classical mechanics, providing insights into how small changes in potential influence the dynamics of scattering processes.
