Determination of the up/down-quark mass within QCD sum rules in the scalar channel

Fang-Hui Yin, Wen-Ya Tian, Liang Tang +1

In this work, we determine up/down-quark mass $m_{q=u/d}$ in the isoscalar scalar channel from both the Shifman-Vainshtein-Zakharov (SVZ) and the Monte-Carlo-based QCD sum rules. T…
