Dual Anti-de Sitter Superalgebras from Partial Supersymmetry Breaking
The partial breaking of supersymmetry in anti\char21{}de Sitter space can be accomplished using two of four dual representations for the massive $\mathrm{OSp}(1,4)$ spin-3/2 multiplet. The procedure gives rise to a set of dual $N=2$ supergravities and supersymmetry algebras.
Massive supermultiplets with spin 3/2
In this paper we construct massive supermultiplets out of appropriate set of massless ones in the same way as massive spin s particle could be constructed out of massless spin s, s−1, ... ones leading to gauge invariant description of massive particle. Mainly we consider massive spin 3/2 supermultiplets in a flat d = 4 Minkowski space both without central charge for N = 1, 2, 3 as well as with central charge for N = 2, 4. Besides, we give two examples of massive N = 1 supermultiplets with spin 3/2 and 2 in AdS4 space.
Resonant Auger decay study of C1s -> pi* core-excited OCS
The present work aims at characterizing short-lived C1s((-1)) pi*((1)) core-excited states of the OCS molecule based on the analysis of the vibrational fine structure and lineshape profiles of the high-resolution resonant Auger decay spectra recorded at the excitation energies along the C1s -> pi* resonance in the binding energy region 15-19eV. Very different behavior in terms of lineshape and resonant enhancement is observed for the (A) over tilde, (B) over tilde and (C) over tilde final states. This is explained by (1) the variation in the C-O bond lengths for the states involved in the electronic relaxation and (2) different contributions in terms of Mulliken population to the molecular orbitals determining the electronic character of the corresponding states. Since the final-state geometries are known from a number of previous experiments and ab initio calculations, the geometry of the C1s((-1)) pi*((1)) intermediate states can be predicted in analogy with e.g. the N-2, CO2 and N2O molecules.
