Description
The perturbative vacuum for models in which fermions are coupled to scalar bosons and contain no derivative coupling for the scalar is shown to be unstable at the one-loop level. The instability is due to fluctuations at a sufficiently short-distance scale and is caused by the fermion loop contributions. Possible instabilities in models which couple fermions to vector bosons only are also discussed
