Lattice calculation of coordinate-space vector and axial-vector current correlators in QCD
JLQCD collaboration, M. Tomii, G. Cossu +5
We study the vector and axial-vector current correlators in perturbative and non-perturbative regimes of QCD. The correlators in Euclidean coordinate space are calculated on the la…
