Description
We present an update of the ongoing computation of the isospin-breaking effects in the Pion Decay Constant from the BMW Collaboration. The calculation is carried out with N$_f$=2+1+1 staggered quarks with a near-physical pion mass and QED$_L$. We present some preliminary results of the valence-valence contribution to the axial-pseudoscalar correlator for different volumes $L=4.2, 6.3, 8.4$ fm at $a=0.1315$ fm and a single volume $L=6$ fm and at $a=0.0952$ fm. We also discuss the next steps and plans.
