WebJul 30, 2024 · We employ the five-flavor scheme, treating the bottom quark as a massless parton while retaining a nonvanishing Yukawa coupling to the Higgs boson. We find that the dependence of the hadronic cross section on the renormalization and factorization scales is substantially reduced.
WebThe determination of the bottom quark mass, as per-formed in [1, 7] relies heavily on the precise measure-ment of R = σ(e+e− → hadrons)/σpt (with σpt = 4πα 2 3s), which enters the moments as defined above.
