【 摘 要 】

The proposed framework is intended to faciliate the search for Lagrangian-basedregularizations that introduce only such coefficients which are not regarded as formalauxiliary parameters that will eventually be disposed of during renormalization. Using thepath-integral formalism, we put forward a new framework for such finite, alternativequantum theories to a given quantum field theory that have no formal auxiliary parameters.The corresponding alternative, perturbative Green functions are acceptably regularizedperturbative expansions of the original Green functions, causal and imply no unphysicalfree particles. To demonstrate that the proposed framework is feasible, we provide analternative to the quantum field theory with the f⁴interaction.
