On the four-loop strong coupling beta-function in the SM
In the talk the leading four-loop contribution to the beta-function of the strong coupling in the SM is discussed. Some details of calculation techniques are provided. Special attention is paid to the ambiguity due to utilized γ5 treatment and a particular prescription with anticommuting γ5 is advoc...

Special attention is paid to the ambiguity due to utilized γ5 treatment and a particular prescription with anticommuting γ5 is advocated.
