Octonionic Realizations of 1-dimensional Extended Supersymmetries. A Classification [PDF]
Mod.Phys.Lett. A18 (2003) 787-798, 2002 The classification of the octonionic realizations of the one-dimensional extended supersymmetries is here furnished. These are non-associative realizations which, albeit inequivalent, are put in correspondence with a subclass of the already classified associative representations for 1D extended supersymmetries.

Journal of High Energy Physics, 2023 With the rapid progress of dark matter direct detection experiments, the attractiveness of the popular bino-dominated dark matter in economical supersymmetric theories is fading.

Nonperturbative unification and extended supersymmetry [PDF]
Physics Letters B, 1989 Abstract We consider the nonperturbative unification scenario proposed by Maiani, Parisi and Petronzio in N =2 supersymmetric extensions of the standard model. Low-energy gauge coupling constants are computed using two-loop renormalization group equations, with a mass spectrum deduced from simple assumptions on the soft terms necessary to break ...

Pure spinor superspace action for D = 6, N = 1 super-Yang-Mills theory
Journal of High Energy Physics, 2018 A Batalin-Vilkovisky action for D = 6, N = 1 super-Yang-Mills theory, including coupling to hypermultiplets, is given. The formalism involves pure spinor superfields.

Goldstino superfields in AdS_4 [PDF]
, 2013 Spontaneous breaking of global supersymmetries results in Goldstino fields which provide a nonlinear realisation of the supersymmetry algebra. A finite supersymmetry transformation of a Goldstino field can be used to generate a superfield whose components provide a linear realisation of the supersymmetry algebra.

Pauli-Lubanski, supertwistors, and the superspinning particle
Journal of High Energy Physics, 2017 We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor formulation of superparticle dynamics.

D-term Dynamical Supersymmetry Breaking Generating Split N=2 Gaugino Masses of Mixed Majorana-Dirac Type [PDF]
, 2012 Under a few mild assumptions, N=1 supersymmetry in four dimensions is shown to be spontaneously broken in a self-consistent Hartree-Fock approximation of BCS/NJL type to one-loop off-shell, in the gauge theory specified by the gauge kinetic function and ...

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, EarlyView.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Supermembrane in D=5: component action [PDF]
, 2013 Based on the connection between partial breaking of global supersymmetry, coset approach, which realized the given pattern of supersymmetry breaking, and the Nambu-Goto actions for the extended objects, we have constructed on-shell component action for N=

Foundations of Ghost Stability
Fortschritte der Physik, EarlyView.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.
