Carlo Maccaferri · arXiv (Cornell University) · 2023
String Field Theory is a formulation of String Theory as a Quantum Field Theory in target space. It allows to tame the infrared divergences of String Theory and to approach its non-perturbative structure and background independence. This article gives a concise overview on the subject and of some of the main recent progress. Note: Review article for Oxford Research Encyclopedia of Physics
