Abstract: Ising field theory represents the basic universality class of criticality in 2D. Besides, it serves as a testground for exact as well as approximate and numerical methods of quantum field theory. I will discuss IFT regarded as the particle theory, and partly substantiate the “McCoy-Wu scenario”. The later proposes the manner in which the particle content of the theory interpolates between its different exactly solvable points. The discussion will be in terms of evolution of the bound-state and virtual-state poles of the elastic scattering amplitude. I will also make remarks about possible fate of some of the resonance poles.
