Abstract

The Higgs-Yukawa model generically contains two possibly largely differing scales. To resum the corresponding logarithms in the effective potential of the model a two-scale subtraction scheme is employed. The beta functions in this scheme depend on the renormalization scale-ratio and a large log’s resummation has to be performed on them. Two partial renormalization group equations are derived and used to compute the two-scale running parameters. Finally, the LO two-scale effective potential is determined and the applicability of decoupling to the present theory is discussed.
