Abstract
We compute the beta functions of the three Standard Model gauge couplings to four-loop order in the modified minimal subtraction scheme. At this order a proper definition of in space-time dimensions is required; however, in our calculation we determine the -dependent terms by exploiting relations with beta function coefficients at lower loop orders.
