We study the nonrelativistic approximation of the (\* 0 , 4 ) d+1 theory. Being trivial for d 4, if d=3 it is either trivial in the two-particle sector or nontrivial in the two-particle sector but with a Hamiltonian unbounded from below in the three-particle sector due to the Thomas effect. If d=2 t
