摘要:The accuaracy of strong coupling constantas is further improved by the high-precision caculation of lattice QCD with Monte-Carlo simulation including the dynamical light (up and down) and strange quarks. I explain recent lattice determination of as using vacuum polarization function computed in dynamical overlap fermion configurations. I also review some other recent results and discuss the future perspective.
