Cosmological correlators in massless ϕ 4-theory and the method of regions
Abstract The calculation of loop corrections to the correlation functions of quantum fields during inflation or in the de Sitter background presents greater challenges than in flat space due to the more complicated form of the mode functions. While in flat space highly sophisticated approaches to Fe...
