QCD lambda parameter from gradient flow

Abstract Starting from the running coupling in the gradient flow scheme, the QCD lambda parameter $$\Lambda _{\,\overline{\!\mathrm MS\!}\;}$$ Λ M S ¯ is determined analytically with respect to the reference scale $$w_0$$ w 0 in the pure gauge theory. A key element is the gluon condensate, which, be... View More
