Renormalization group coupling flow of SU(3) gauge theory

We present our new results on the renormalization group coupling flow obtained i n 3 dimensional coupling space $({\beta }_{11},{\beta }_{12},{\beta }_{twist})$. The value of ${\beta }_{twist}$ turns out to be small and the coupling flow projected on $({\beta }_{11},{\beta }_{12})$ plane is very similar with the previous result obtained in the 2 dimensional coupling space.
