Abstract We consider the infinite volume Dirichlet (or half-Dirichlet)P(φ)2 quantum field theory withP(X)=aX 4+bX 4+bX 2−μX(a〉0). If μ≠0 there is a positive mass gap in the energy spectrum. If the gap vanishes as μ → 0, it goes to zero no faster than linearly yielding a bound on a critical exponent.
