BPS representations of 5-dimensional supersymmetry algebras are classified. For BPS states preserving 1/2 the supersymmetry, there are two distinct classes of multiplets for N = 4 supersymmetry and three classes for N = 8 supersymmetry. For N = 4 matter theories, the two 1/2 supersymmetric BPS multiplets are the massive vector multiplet and the massive self-dual 2-form multiplet. Some applicati...

Scenarios of supersymmetry breaking at various scales from TeV to GUT to the string are generated. A previous analysis generated the value of the experimentally measured cosmological constant from supersymmetry breaking at the TeV scale. Via a reorganization of the perturbative series, values of the cosmological constant are generically reconcilable with supersymmetry breaking scenarios having ...

This study examines on-shell supersymmetry breaking in the Abelian $\mathcal{N}=1$ Chern-Simons-matter model within a three-dimensional spacetime. The classical Lagrangian is scale invariant, but two-loop radiative corrections to effective potential break this symmetry, along with gauge and supersymmetry. To investigate issue, renormalization group equation used calculate potential.

Department of Physics, Tamkang University, Tamsui 25137, Taiwan, R.O.C. Abstract We recall the importance of recognizing the different mathematical nature of various concepts relating to PT -symmetric quantum theories. After clarifying the relation between supersymmetry and pseudo-supersymmetry, we prove generically that nonlinear pseudo-supersymmetry, recently proposed by Sinha and Roy, is jus...

We study the phenomenon of accidental or “emergent” supersymmetry within gauge theory and connect it to the scenarios of Split Supersymmetry and Higgs compositeness. Combining these elements leads to a significant refinement and extension of the proposal of Partial Supersymmetry, in which supersymmetry is broken at very high energies but with a remnant surviving to the weak scale. The Hierarchy...

The form of realistic space-time supersymmetry is fixed, by HaagLopuszanski-Sohnius theorem, either to the familiar form of Poincare supersymmetry or, in massless case, to that of conformal supersymmetry. We question necessity for such strict restriction in the context of theories with broken symmetries. In particular, we consider parabose N = 4 algebra as an extension of conformal supersymmetr...

A bstract We initiate a systematic study of the self-interactions massive spin-2 “graviton” consistent with up to $$ \mathcal{N} N = 4 supersymmetry. Using recently developed on-shell superspace formalism, we construct most general set cubic graviton amplitudes in form all supersymmetry and Lorentz invariance...
