Analysis of the interpolating currents of baryons: anomalous dimension

Abstract

The anomalous dimensions for the interpolating currents of baryons are indispensable inputs in a serious QCD analysis of baryon. However, the results in the literature are vague. In view of this, in this work, we investigate the one-loop anomalous dimensions for some interpolating currents such as those of ${\Lambda }_Q$ and proton. Under the requirement of precise testing the Standard Model, this study is essential and significant for the QCD analysis in the future.
