Precision Measurement of the Strong Coupling Constant in QCD
The article details the precise determination of the strong coupling constant αs in quantum chromodynamics (QCD) using lattice QCD, reducing its uncertainty to five parts per mille. This advancement enhances the accuracy of collider predictions and supports future high-precision experiments like the High-Luminosity LHC and FCC-ee.
