Effective field theory offers a general model independent approach to study the low energy behavior of physical systems in several different branches of physics; most importantly in quantum electrodynamics, standard model of elementary particle physics and condensed matter physics.

In describing a physical system, one can normally focus on the degrees of freedom that are relevant at the distance scales under consideration. For example, although it is well known that quantum mechanics is a more fundamental theory than classical mechanics, it would be difficult to describe the earth’s motion around the sun by use of quantum ...

If we take quantum gravity to be a theory that replaces GR at high energy scales (i.e. a micro-theory of spacetime), then GR must be understood as an effective theory, meaning it is thought to be valid only at large length-scales compared to the characteristic length-scale of quantum gravity (perhaps the Planck length). The framework of effective field

Effective field theories (EFTs) are a highly important topic in Quantum Field Theory. Here we are going to shortly present some important highlights as well as the renormalization group equations for the Wilson coefficients. Afterwards we shall focus on one illustrative example and present the \(\textit{matching}\) procedure at the one-loop level.
