WebFeb 19, 2024 · Perturbation theory assumes that there is a small dimensionless parameter in the theory. To perform perturbative calculations, one would make an asymptotic expansion in terms of this dimensionless parameter. The first term in the expansion represents the unperturbed result; the second term is the first perturbation; and so forth.
