An Introduction to Conformal Field Theory

From an abstract point of view conformal ﬁeld theories are Euclidean quantum ﬁeld theories that are characterised by the property that their symmetry group contains in addition to the Euclidean symmetries local conformal transformations i e transformations that preserve angles but not lengths

What is a conformal transformation in field theory?
Conformal transformations are coordinate trans- formations that preserve the angles (i.e. scalar products) between vectors in a space (or space-time).
Several excellent treatments of Conformal Field Theory in the literature which have inspired the presentation of this topic in this book.
In quantum field theory, conformal symmetry plays a crucial role in both QED and QCD.
In QED, conformal symmetry is used to describe the behavior of electromagnetic fields and the interactions between charged particles.

What is basic conformal field theory?

A conformal field theory (CFT) is a field theory which is invariant under these transfor- mations.
This means that the physics of the theory looks the same at all length scales.
Conformal field theories care about angles, but not about distances.

What is conformal field theory action?

A conformal field theory is unitary if its space of states has a positive definite scalar product such that the dilation operator is self-adjoint.
Then the scalar product endows the space of states with the structure of a Hilbert space.
