A new analysis of the pQCD contributions to the electroweak parameter ρ using the single-scale approach of principle of maximum conformality
It has been observed that conventional renormalization scheme and scale ambiguities for the pQCD predictions can be eliminated by using the principle of maximum conformality (PMC). However, being the intrinsic nature of any perturbative theory, there are still two types of residual scale dependences...
