A Conformal Field Theory Primer in $D\ge 3$

This primer is an introduction to Conformal Field Theory in $D\ge 3$. It is designed to introduce the reader to many of the important foundational concepts and methods in CFT. In it, pig picture ideas are prioritized over technical details, which can be found in many of the other excellent reviews that already exist. It is written primarily with upper division undergraduate Physics majors, master’s students, and PhD students in mind. However, it should additionally be useful to anyone who is interested in learning the basics of CFT and has some foundation in undergraduate Physics coursework.
