Abstract

The proposed framework is intended to faciliate the search for Lagrangian-based regularizations that introduce only such coefficients which are not regarded as formal auxiliary parameters that will eventually be disposed of during renormalization. Using the path-integral formalism, we put forward a new framework for such finite, alternative quantum theories to a given quantum field theory that have no formal auxiliary parameters. The corresponding alternative, perturbative Green functions are acceptably regularized perturbative expansions of the original Green functions, causal and imply no unphysical free particles. To demonstrate that the proposed framework is feasible, we provide an alternative to the quantum field theory with the φ4 interaction.<br />Predlažu se postavke čiji je cilj olakšanje traženja regularizacija uz primjenu samo onih koeficijenata koji se ne smatraju formalnim pomoćnim parametrima, a koji se kasnije odbacuju renormalizacijom. Rabeći formalizam integrala po putevima, izlažemo novu postavku za takve konačne, inačne kvantne teorije danoj kvantnoj teoriji polja koja nema formalne pomoćne parametre. Odgovarajuće inačne perturbativne Greeenove funkcije su prihvatljivo regulirani perturbativni razvoji izvornih Greenovih funkcija, kauzalni su i ne uključuju nefizikalne slobodne čestice. Radi pokazivanja da je predložena postavka ostvariva, izlažemo inačicu kvantnoj teoriji polja s φ4 interakcijom.
