Lattice QCD evaluation of π⁻→π⁺ee matrix elements at physical pion mass with a new around-the-world subtraction technique and RI/SMOM renormalization that reduces uncertainties and cross-checks prior results.
moves these effects directly from the lattice data, thereby achieving stable plateaus in the ratio of three-point to two-point correlation functions
