Abstract

The limits g → large, M → large with (g 3/M)  =  const. of the 1+1-dimensional Yukawa model are discussed. The conclusion of the results on bound states of the Yukawa model in this limit (obtained in arXiv:0908.4510v3 [hep-th]) is taken into account. It is found that model reduces to an effective non-local ϕ 3 theory in this limit. Causality violation also is observed in this limit.
