Abstract
The SU(2) gauge system with fixed-length Higgs fields is studied in the adjoint representation. High-statistics Monte Carlo simulations on lattice sizes between L = 4 and L = 8 give evidence that the transition for large Higgs coupling is of first order. For small Higgs coupling the transition signal may be interpreted as a very weak first- or a second-order transition. In the latter case a hitherto unknown tricritical point in the phase diagram is expected.
