摘要:

AbstractA review is given of the present state of experimental and theoretical knowledge of the proton‐proton and antiproton‐proton forward scattering, with special attention to applications of phenomenological dispersion theory in elucidating this interaction. The topics covered include the treatment of unphysical region, low‐energy parameterizations, dispersion relation calculations of the real parts and the meson‐nucleon coupling constants, analyses of the data by recently developed numerical analytic continuation techniques, high‐energy phenomenology, and evaluation of

摘要:

AbstractWe study irreducible and reducible representations of the generalized Lie algebra of Wess and Zumino. The algebra is integrated to a group with the help of Grassmann algebras and the representations of the algebra are made into representations of the group. We construct invariant sesquilinear forms that are positive definite for the Wess‐Zumino algebra over the complex field. We define irreducible superfields for any spinJas specific realizations of such representations. All superfields appearing in the literature are either equivalent to one of these or built up out of these superfield

摘要:

AbstractCovariant free field equations are systematically derived for irreducible and bilinear superfields from representation theory of the Wess‐Zumino algebra. Interactions are introduced by covariance arguments alone or by the principle of local gauge invariance. Finally we construct propagators for massive superfield
