Hadronic uncertainties versus new physics for the W boson mass and Muon g − 2 anomalies

Abstract

The tension between measured W mass and its Standard Model prediction might arise from uncertainties in the hadronic contribution, and the same is true for the muon g − 2. Here, the authors show that such a common origin for the two anomalies is unlikely, while a model involving leptoquarks might explain them both.
