(2019). Strong Running Coupling from the Gauge Sector of Domain Wall Lattice QCD with Physical Quark Masses. Physical Review Letters, 122(16). DOI: https://doi.org/10.1103/physrevlett.122.1620020031-9007http://hdl.handle.net/10272/18370We report on the first computation of the strong running coupling at the physical point (physical pion mass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of domain wall fermions. We find MSðm2 ZÞ ¼ 0.1172ð11Þ, in remarkably good agreement with the world-wide average. Our computational bridge to this value is the Taylor-scheme strong coupling, which has been revealed of great interest by itself because it can be directly related to the quark-gluon interaction kernel in continuum approaches to the QCD bound-state problem.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Gauge SectorDomain Wall LatticeQCDPhysical Quark Massesjournal article10.1103/PhysRevLett.122.162002open access
