Adinkra Isomorphisms and `Seeing' Shapes with Eigenvalues
We create an algorithm to determine whether any two graphical representations
(adinkras) of equations possessing the property of supersymmetry in one or two
dimensions are isomorphic in shape. The algorithm is based on the determinant
of `permutation matrices' that are defined in this work and derivable for any
adinkra.Comment: LaTeX twice, 23 pages, 7 figure
On 4D, N = 1 Massless Gauge Superfields of Higher Superspin: Integer Case
We present an alternative method of exploring the component structure of an
integer super-helicity Y=s (for any integers) irreducible representation of the
Super-Poincare group. We use it to derive the component action and the SUSY
transformation laws. The effectiveness of this approach is based on the
equations of motion and their properties, like Bianchi identities. These
equations are generated by the superspace action when it is expressed in terms
of prepotentials. For that reason we reproduce the superspace action for
integer superspin, using unconstrained superfields. The appropriate, to use,
superfields are dictated by the representation theory of the group and the
requirement that there is a smooth limit between the massive and massless case.Comment: LaTeX twice, 23 pp
Progress on cubic interactions of arbitrary superspin supermultiplets via gauge invariant supercurrents
We consider cubic interactions of the form between a massless integer
superspin supermultiplet and two massless arbitrary integer or half integer
superspin supermultiplets. We focus on non-minimal interactions generated
by gauge invariant supercurrent multiplets which are bilinear in the superfield
strength of the superspin supermultiplet. We find two types of consistent
supercurrents. The first one corresponds to conformal integer superspin
supermultiplets, exist only for even values of , for arbitrary
values of and it is unique. The second one, corresponds to Poincar\'e
integer superspin supermultiplets, exist for arbitrary values of and
A Theory of Spinning Particles for Large N-extended Supersymmetry
An explicit construction of theories of spinning particles, both massive and
massless, is given with arbitrary extended supersymmetry on the world-line. As
an application of our results, we give a universal description of 3D (and via
truncation all lower dimensional) supersymmetric scalar multiplets with
arbitrary N-extended supersymmetry.Comment: 11 pages, Latex fil
Minimal Superspace Vector Fields for 5D Minimal Supersymmetry
We investigate a minimal superspace description for 5D superconformal Killing
vectors. The vielbein appropriate for AdS symmetry is discussed within the
confines of this minimal supergeometry.Comment: 10 page
SUSY Equation Topology, Zonohedra, and the Search for Alternate Off-Shell Adinkras
Results are given from a search to form adinkra-like equations based on
topologies that are not hypercubes. An alternate class of zonohedra topologies
are used to construct adinkra-like graphs. In particular, the rhombic
dodecahedron and rhombic icosahedron are studied in detail. Using these
topological skeletons, equations similar to those of a supersymmetric system
are found. But these fail to have the interpretation of an off-shell
supersymmetric system of equations.Comment: 29 pages, 4 figure
On 4D, N = 1 Massless Gauge Superfields of Higher Superspin: Half-Odd-Integer Case
We present an alternative method to explore the off-shell component structure
of theories that describe half-integer super-helicities Y=s+1/2 (where sis any
positive integer). We use it to derive the component action, component SUSY
transformation laws, and count the component-level degrees of freedom involved.
This counting will give us clues about N=2 representations. The foundation of
the process relies on the superfield equations of motion, generated by
variation of a superspace action expressed in terms of prepotentials. Using
this approach we reproduce the half-integer super-helicity superspace action
using unconstrained superfields.Comment: LaTeX twice, 31 pp
A Codicil To Massless Gauge Superfields of Higher Integer Superspins
We study theories of 4D, N=1 supersymmetric massless, arbitrary integer
superspins. A new state-of-the art is being established by the discovery of a
new series of such theories for arbitrary superspin Y (Y=s for any integer s)
The lowest member of the series is surprisingly found to be a previously
established formulation of the spin (3/2, 1) supermultiplet
A Dynamical Theory for Massive Supergravity
We present a new massive theory of superspin Y=3/2 which has non-minimal
supergravity as it's massless limit. The new result will illuminate the
underlying structure of auxiliary fields required for the description of
arbitrary massive half-integer superspin systems.Comment: LaTeX twice, 12 ppg, 1 figur
A Truly Crazy Idea About Type-IIB Supergravity and Heterotic Sigma-Models
We construct an explicit and manifestly (1,0) heterotic sigma-model where the
background fields are those of 10D, N=IIB supergravity.Comment: 10 Pages, Latex (self contained macros
