摘要:

AbstractRecent development in the quantum field theory approach to a unified description of the pion‐deuteron and nucleon‐nucleon interaction processes is reviewed. The physical ground and the structure of the equations for such processes derived in the last few years in the literature are discussed. The non‐linear character of the equations under consideration is pointed out and the iteration procedure for their solution is suggested to avoid the non‐li

摘要:

AbstractWe give a review of the renormalization and short distance properties of path ordered phase factors in nonabelian gauge field theories. It includes nonlocal gauge invariant meson, baryon and gluonium operators constructed with the help of such phase factors. Furthermore, the renormalization properties of functional derivatives of phase factors as they are needed in dynamical equations are considered. The discussion is based on an one dimensional auxiliary field formalism which enables the application of the usual language of local Green's functions.
