Reconsideration of the QCD corrections to the ${\eta }_c$ decays into light hadrons using the principle of maximum conformality

Bo-Lun Du, Xing-Gang Wu, Jun Zeng +2

In the paper, we analyze the ${\eta }_c$ decays into light hadrons at the next-to-leading order QCD corrections by applying the principle of maximum conformality (PMC). The relativistic…
