τ̃ searches at future e+e− colliders [PDF]
EPJ Web of ConferencesThe direct pair-production of the superpartner of the τ-lepton, the τ̃, is one of the most interesting channels to search for SUSY in: the τ̃ is likely to be the lightest of the scalar leptons, and is one of the most experimentally chalanging ones.

Minimal R+R2 supergravity models of inflation coupled to matter
Physics Letters B, 2014 The supersymmetric extension of “Starobinsky” R+αR2 models of inflation is particularly simple in the “new minimal” formalism of supergravity, where the inflaton has no scalar superpartners.

Resonant slepton production and right sneutrino dark matter in left-right supersymmetry
Journal of High Energy Physics, 2017 Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions.

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.

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.

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

Noether-Wald and Komar charges in supergravity, fermions, and Killing supervectors in superspace [PDF]
Journal of Physics: Conference SeriesThe supersymmetry properties of Killing vectors and spinors in supergravity theory can be clarified by relating them to Killing supervectors in the supergravity superspace.

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.

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 ...
