Non-perturbative determination of the Λ-parameter in the pure SU(3) gauge theory from the twisted gradient flow coupling

Abstract We evaluate the Λ-parameter in the MS¯ $$ \overline{\mathrm{MS}} $$ scheme for the pure SU(3) gauge theory with the twisted gradient flow (TGF) method. A running coupling constant g TGF2(1/L) is defined in a finite volume box with size of L 4 with the twisted boundary condition. This define...
