Description
We present our updated study of the nonperturbative running coupling constant in Twisted Polyakov Loop (TPL) scheme.
We study the larger lattice size and the lower $\beta$ region ($\beta
\geq 4.5$) in the case of SU(3) Nf=12.
We discuss in detail the step scaling function, the running coupling constant, and the nonperturbative beta function using these updated data.
We also discuss the comparison with the perturbative two-loop results.
