Title	The QCD Adler function and the muon g-2 anomaly from Renormalons
Abstract	I will talk about the Adler function in Quantum Chromodynamics in terms of a transseries representation within a resurgent framework. The approach is based on a Borel-Ecalle resummation of the infrared renormalons, which, combined with an effective running for the strong coupling, gives values in good quantitative agreement with the experimental Adler function data. We discuss its impact on the muon's anomalous magnetic moment. Without the need for new physics and using our expression for the Adler function, we show that it is possible to saturate the current discrepancy between the best Standard Model value for the muon's anomalous magnetic moment and the one obtained from data.
