The $$\Upsilon (1S)$$ Υ(1S) leptonic decay using the principle of maximum conformality

Abstract In the paper, we study the $$\Upsilon (1S)$$ Υ(1S) leptonic decay width $$\Gamma (\Upsilon (1S)\rightarrow \ell ^+\ell ^-)$$ Γ(Υ(1S)→ℓ+ℓ-) by using the principle of maximum conformality (PMC) scale-setting approach. The PMC adopts the renormalization group equation to set the correct moment...
