Abstract: In perturbative QFT including higher order corrections is often important for improving the accuracy of our predictions. One complication to computing these corrections are the (potentially divergent) integrals which arise in loop/virtual corrections. We will begin by briefly motivating the connection between loop corrections and integrals and introduce the concept of regulating divergent integrals. A procedure for evaluating regulated integrals, known as Sector Decomposition, and a tool which implements it, SecDec, will be introduced. The important features of the procedure will be summarised and, time permitting, a typical use case will be demonstrated.
