Inflation correlators at the one-loop order: nonanalyticity, factorization, cutting rule, and OPE
Abstract Inflation correlators with one-loop massive exchange encode rich information about the dynamics of the massive loop particles. Their nonanalytic behavior in certain soft limits leads to characteristic oscillatory pattern, which is the leading signal of many particle models of cosmological c...
