# Up- and down-quark masses from QCD sum rules

@article{Dominguez2019UpAD, title={Up- and down-quark masses from QCD sum rules}, author={Cesareo A. Dominguez and Alexes Mes and Karl Schilcher}, journal={Journal of High Energy Physics}, year={2019}, volume={2019}, pages={1-14} }

A bstractThe QCD up- and down-quark masses are determined from an optimized QCD Finite Energy Sum Rule (FESR) involving the correlator of axial-vector current divergences. In the QCD sector this correlator is known to five loop order in perturbative QCD (PQCD), together with non-perturbative corrections from the quark and gluon condensates. This FESR is designed to reduce considerably the systematic uncertainties arising from the hadronic spectral function. The determination is done in the…
