Using the CLEO detector at the Cornell Electron Storage Ring, we have made a measurement of R=sigma(e+e- ->hadrons)/sigma(e+e- ->mu+mu-) =3.56+/-0.01+/-0.07 at ECM=10.52 GeV. This implies a value for the strong coupling constant of alpha_s(10.52 GeV)=0.20+/-0.01+/-0.06, or alpha_s(M_Z)=0.13+/-0.005+/-0.03.

  1. Calibrated correlation between heavy-quark masses and Hadronic Vacuum Polarization observables at the precision frontier

    hep-ph 2026-08 conditional novelty 7.0 of 10

    A generalized QCD sum rule with the HVP kernel as weight simultaneously determines heavy-quark masses and their muon g-2 contributions, with reduced uncertainty.

  2. Perturbative QCD fitting of KEDR and BESIII $e^+e^-$ data for R(s) and $\alpha_s$ determination

    hep-ph 2026-03 unverdicted novelty 5.0 of 10

    Fits of combined KEDR and truncated BESIII data yield α_s(M_Z)=0.1179 (NLO), 0.1221 (NNLO), 0.1313 (N3LO), with the rise attributed to π² analytic-continuation effects.
