  Lattice gauge field theories may suffer from unphysical "bulk" phase
transitions at strong lattice gauge coupling. We introduce a one-parameter
family of lattice SU(N) gauge actions which, when used in combination with an
HMC update algorithm, prevents the appearance of the bulk phase transition. We
briefly discuss the (presumed) mechanism behind the prevention of the bulk
transition and present test results for different SU(N) gauge groups.
