[en] We provide a tensor calculus for n-number of N = (1, 0) linear multiplets in six dimensions. The coupling of linear multiplets is encoded in a function F that is subject to certain constraints. We provide various rigid and local supersymmetric models depending on the choice of the function F and provide an interesting off-diagonal superinvariant, which leads to an R supergravity upon elimination of auxiliary fields.
[en] A simple method for non-empirical ligand field multiplet calculations for transition metal L-edge spectra is presented. Ligand field splittings and anisotropic scaling factors for Coulomb integrals are obtained from density functional theory. The method is applied to transition metal monoxide solids and nickel and cobalt phthalocyanines molecules and good agreement with experiment is obtained.
[en] We present a superconformal tensor calculus for an arbitrary number of five dimensional N=2 linear multiplets. We also demonstrate how to construct higher derivative invariants, and produce higher order supersymmetric off-diagonal models. Finally, we show the procedure required for the derivation of the supersymmetric completion of the non-Abelian F"4 action.
[en] The structure of on-shell and off-shell 2D (4,4) supersymmetric scalar multiplets is investigated, in components and in superspace. We reach the surprising result that there exist eight distinct on-shell versions and an even greater variety of off-shell ones. The off-shell generalised tensor and relaxed N=4 multiplets are introduced in superspace, and their universal invariant self-interaction is constructed. (orig.)
[en] It is shown how to incorporate multiplets with central charges in superconformal gravity. The linear and scalar N = 2 multiplets are presented, and the full superconformal action of scalar multiplets with gauged central charge is given. (orig.)
[en] A theory of fusion based upon the solutions of the nucleon equations that have opposite signs of energy, is used to extend the calculus of mass differences between the elements (pions or kaons) of a meson multiplet. Five results are given (the nucleon which specifies the Yukawa range being excluded), four of them are in conformity with experiments, the fifth one can be obtained approximately
[fr]En utilisant une theorie de la fusion fondee sur les solutions de l'equation du nucleon dont les energies sont de signes contraires, on etend aux pions et aux kaons le calcul des differences de masse. Sans tenir compte du nucleon qui sert a ajuster le rayon d'action de Yukawa, on obtient cinq resultats dont quatre sont en accrod tre exact avec l'experience, le cinquieme etant assez approche
