摘要:

AbstractThe soft renormalization procedure, proposed by Gomes, Lowenstein and Zimmermann, is applied to the construction of a pre‐scaling (soft) parametrization of renormalized perturbation theory. The global pre‐scaling parameters are directly incorporated into the Lagrangian; resummation problems and subsidiary condition are completely avoided. For theA4‐theory with linear symmetry breaking and the spontaneous limit we give a detailed structural investigation in terms of partial differential equations to all orders of perturbation theory. In the second part the scaling structure and “marginal” corrections to scaling are reconsidered in terms of the soft parametrization. The pre‐scaling parametrization represents a powerful tool in dealing with the field theoretical aspects of critica

AbstractFor any massm≧ 0 and arbitrary spin, free relativistic quantum fields are constructed using the same formulas form>0 and form= 0. The transformation properties of these fields underP,C,Tand some questions concerning super‐selection rules are discus
