Effective Field Theory,s well as the renormalization group equations for the Wilson coefficients. Afterwards we shall focus on one illustrative example and present the . procedure at the one-loop level. The infrared behaviour of EFTs is also covered with this example.

Optical Theorem,be a useful cross check for some calculations. In this chapter we will explicitly deduce the standard form of the optical theorem and try to establish a robust and transparent notation. We will also take an illustrative example and recover the well known Breit-Wigner approximation for unstable particle propagators.

Dirac Algebra,g relations among the various Dirac matrices and we present the basics of calculating spinor traces. The tools given here can be used to further calculate lengthy and more complicated traces involving Dirac matrices. The transformation of spinors under Lorentz transformations is also presented consi
