Axiomatic restrictions on scattering amplitudes of hadrons

Problems of expsrimental verification of the quantum field theoretical principles by experimental test of any one of physical corollaries of the axiomatic quantum field theory are shortly discussed. A selective review of available axiomatic restrictions on scattering amplitudes of hadrons is given.The author is very indebted to E. P.Sabad, I. Yu.Krivsky, V. I.Kelemen, and Yu. A.Xaveri for the help offered to him during the preparation of this review. The author is especially indebted to Academician N. N.Bogolyubov for his approval of Theorem XXVIII before publishing it in Ref. 67], as well as to Prof. M. I.Podgoretsky (Dubna) and Prof. V. Ya.Fajnberg (Moscow) for numerous discussions of this theorem and Prof. Yu. M.Shirokov (Moscow) for a preciseful stimulating remark.
