Tuning to N = 2 supersymmetry in the SU(2) adjoint Higgs-Yukawa model Original Research Article

The N = 2 supersymmetric continuum limit is investigated in the SU(2) adjoint Higgs-Yukawa model using lattice perturbation theory. In the one-loop renormalization group equations a non-trivial infrared fixed point of coupling ratios is found. The phase structure at weak couplings is determined by a numerical study of the one-loop effective potential.
