This updated analysis includes new lattice data, at smaller lattice spacings and reaching shorter distances, the use of better suited perturbative expressions to compare with data in a wider distance range, and a comprehensive and detailed estimate of the error sources that contribute to the uncertainty of the final result. Our updated value for α s at the Z -mass scale, M Z , is α s ( M Z ) = 0.116 6 + 0.0012 − 0.0008 , which supersedes our previous result.20 p.application/pdfeng(c) American Physical Society, 2014Cromodinàmica quànticaFísica de partículesGran Col·lisionador d'HadronsQuantum chromodynamicsParticle physicsLarge Hadron Collider (France and Switzerland)info:eu-repo/semantics/article6460042019-04-02info:eu-repo/semantics/openAccess
