Description
Renormalons are non-perturbative effects which are manifested in perturbative series. While they appear in important QFTs, they are in general poorly understood. In this talk I will explain how to analytically find these non-perturbative effects in the free energy starting from the Bethe ansatz integral equations. I will also present a short introduction to the framework of resurgence and to how it is a key tool in the analysis of non-perturbative effects in QFT.
