Isospin-breaking effects in the three-pion contribution to hadronic vacuum polarization

A bstract Isospin-breaking (IB) effects are required for an evaluation of hadronic vacuum polarization at subpercent precision. While the dominant contributions arise from the e + e − → π + π − channel, also IB in the subleading channels can become relevant for a detailed understanding, e.g., of the...
