This question already has an answer here:

In QFT, it is easy to find resource on a free scalar quantum field theory. When I tried to search for a free conformal field theory, I could not find a good resource.

Can anyone either give some information with regards to how free conformal field theory would look like, or give some links that would help?

Before answering, please see our policy on resource recommendation questions. Please write substantial answers that detail the style, content, and prerequisites of the book, paper or other resource. Explain the nature of the resource so that readers can decide which one is best suited for them rather than relying on the opinions of others. Answers containing only a reference to a book or paper will be removed!
