An Update on the Isospin-Breaking Effects in the Pion Decay Constant with Staggered Quarks
Abstract
We present an update on the ongoing computation of the isospin-breaking effects in the Pion Decay Constant from the BMW Collaboration. The calculation is carried out with Nf=2+1+1 staggered quarks with a near-physical pion mass and QEDL. We give an update on the isosymmetric value and the current determination used to compute the gradient-flow scale w0, then we present some preliminary results of the valence-valence contribution to the axial-pseudoscalar correlator for different volumes and lattice spacings. We also discuss the next steps and plans.
