Saxion cosmology for thermalized gravitino dark matter
Journal of High Energy Physics, 2017 In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Charting generalized supersoft supersymmetry
Journal of High Energy Physics, 2018 Without any shred of evidence for new physics from LHC, the last hiding spots of natural electroweak supersymmetry seem to lie either in compressed spectra or in spectra where scalars are suppressed with respect to the gauginos.

Supersymmetric inflation from the fifth dimension
Journal of High Energy Physics, 2019 We develop a supersymmetric bi-axion model of high-scale inflation coupled to supergravity, in which the axionic structure originates from, and is protected by, gauge symmetry in an extra dimension. While local supersymmetry (SUSY) is necessarily Higgsed

Journal of High Energy Physics, 2019 We revisited the formalism of 110 polarized scattering equation by Geyer and Mason from the perspective of spinor frame approach and spinor moving frame formulation of the 110 ambitwistor superstring action.

Phenomenology of SUSY with scalar sequestering
, 2008 The defining feature of scalar sequestering is that the MSSM squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultraviolet boundary condition - scalar masses vanish while gaugino and Higgsino

Precision Supersymmetry Measurements at the e^-e^- Collider [PDF]
, 1998 Measurements of supersymmetric particle couplings provide important verification of supersymmetry. If some of the superpartners are at the multi-TeV scale, they will escape direct detection at planned future colliders.

Search for scalar superpartners of the top quark
Physics Letters B, 1985 Abstract The phenomenology of top squarks is investigated in the framework of a large class of models based on spontaneously-broken local supersymmetry, in which the top quark often has a scalar superpartner lighter than m t . We find that two-body (one-loop) decays of top squarks lighter than top quarks dominate over four-body (tree-level) decays.

Dark gauge-mediated supersymmetry breaking with a massless dark photon
Journal of High Energy PhysicsWe study dark gauge-mediated supersymmetry breaking (dark GMSB) in a theory with a new unbroken U(1) D local symmetry and massless dark photon. Messenger fields charged under both Standard Model and dark gauge symmetries produce new soft supersymmetry ...

Minimal Supergravity with m_0^2 < 0
, 2005 We extend the parameter space of minimal supergravity to negative values of m_0^2, the universal scalar mass parameter defined at the grand unified scale.
