Scientific paper

In this paper we provide an alternative method to compute correlation functions in the in-in formalism. We develop a modified set of Feynman rules that allows for an easier computation of loop corrections. With respect to the standard in-in formalism (where the diagrammatic representation is very compact but the evaluation of each diagram is rather involved and contains many different contributions), in our formulation the major effort is devoted to drawing the diagrams, while their mathematical interpretation is straightforward. Our method is particularly suitable for applications to cosmology.
