Description
Abstract: Renormalizable QFT has two types of non-perturbative contributions: instantons and renormalons. However, little is known about the latter. In this talk, I will review the program of extracting semi-classical expansions from the Bethe Ansatz in integrable QFTs, its results and some open challenges. I will focus on the finite N results for instantons and renormalons, including previously the new families of renormalons discovered by these methods
