Description

We examine the compatibility of the different data sets of e^+e^- -> pi^+ pi^- and tau^- -> pi^- pi^0 nu_tau accounting for the required isospin-breaking between both sources of input to a_mu^{HVP,LO}|_{pipi}, which is responsible for the current conundrum in the data-based SM prediction of a_mu.
