Supersymmetry without Supersymmetry [PDF]

Physics Letters B, 1997
We present four-dimensional M-theory vacua with N>0 supersymmetry which, from the perspective of perturbative Type IIA string theory, have N=0. Such vacua can appear when the compactifying 7-manifold is a U(1) fibration.

A Solution to the $μ$ Problem in Gauge-mediated Supersymmetry-breaking Models [PDF]

Phys.Lett. B400 (1997) 109-111, 1997
We point out that a sector required to set the cosmological constant to zero in gauge-mediated supersymmetry-breaking models naturally produces a supersymmetry-invariant mass ($\mu$ term) for Higgs doublets of the order of the electroweak scale. Since this new sector preserves the supersymmetry, it does not generate supersymmetry-breaking masses for ...

Extended supersymmetry and its reduction on a circle with point singularities [PDF]

J.Phys. A38 (2005) 8053-8082, 2005
We investigate $N$-extended supersymmetry in one-dimensional quantum mechanics on a circle with point singularities. For any integer $n$, $N=2n+1$ supercharges are explicitly constructed in terms of discrete transformations, and a class of singularities compatible with supersymmetry is clarified. In our formulation, the supersymmetry can be reduced to $

Sigma models with off-shell N=(4,4) supersymmetry and noncommuting complex structures [PDF]

JHEP 1009:055,2010, 2009
We describe the conditions for extra supersymmetry in N=(2,2) supersymmetric nonlinear sigma models written in terms of semichiral superfields. We find that some of these models have additional off-shell supersymmetry. The (4,4) supersymmetry introduces geometrical structures on the target-space which are conveniently described in terms of Yano f ...

Supersymmetry

Proceedings of the XVII International Workshop on Deep-Inelastic Scattering and Related Topics, 2009
The determination of supersymmetric parameters at the LHC in favorable as well as difficult scenarios is presented. If discovered and measured at the LHC and the ILC, supersymmetry may provide a link between collider physics and cosmology.Comment ...

Weak Scale Supersymmetry Emergent from the String Landscape [PDF]

Entropy
Superstring flux compactifications can stabilize all moduli while leading to an enormous number of vacua solutions, each leading to different 4−d laws of physics.

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.

Resurgent Supersymmetry and String Theory [PDF]

, 2014
We study a realization of accidental supersymmetry in type IIB string theory as a proof-of-principle of the mechanism and as a prototype of the strong sector present in resurgent supersymmetry, a warped UV-completion of natural supersymmetry. We first introduce the mechanism of accidental supersymmetry as a way of producing a supersymmetric spectrum in

General covariance, and supersymmetry without supersymmetry [PDF]

Physical Review D, 1996
An unusual four-dimensional generally covariant and supersymmetric SU(2) gauge theory is described. The theory has propagating degrees of freedom, and is invariant under a local (left-handed) chiral supersymmetry, which is half the supersymmetry of ...
