摘要

We present results for the QED and strong isospin breaking corrections to the hadronic vacuum polarization using N_f=2+1 Domain Wall fermions. QED is included in an electro-quenched setup using two different methods, a stochastic and a perturbative approach. Results and statistical errors from both methods are directly compared with each other.
