The heavy quarkonium inclusive decays using the principle of maximum conformality
Abstract The next-to-next-to-leading order (NNLO) pQCD correction to the inclusive decays of the heavy quarkonium $$\eta _Q$$ ηQ (Q being c or b) has been done in the literature within the framework of nonrelativistic QCD. One may observe that the NNLO decay width still has large conventional renorm...
