Journal of High Energy Physics, 2017 We consider a U(1)′ extended supersymmetric model with a right-handed neutrino superfield which can generate light neutrino mass by Type I seesaw mechanism. The lighter superpartner of the right-handed neutrino could be the scalar dark matter.

Reheating after inflation by supersymmetry breaking
European Physical Journal C: Particles and Fields, 2021 We study reheating after the end of inflation in models where the inflaton is the superpartner of goldstino and is charged under a gauged U(1) R-symmetry. We consider two classes of models – one is small field characterized by an almost flat Kähler space,

Compressed supersymmetry and natural neutralino dark matter from top squark-mediated annihilation to top quarks [PDF]
, 2007 The parameters of the Minimal Supersymmetric Standard Model appear to require uncomfortably precise adjustment in order to reconcile the electroweak symmetry breaking scale with the lower mass limits on a neutral Higgs scalar boson.

Gravitino cosmology helped by a right handed (s)neutrino
Physics Letters B, 2022 In this paper, we discuss interesting scenarios resulting from the interplay between the gravitino and the lightest right-handed (s)neutrino. We consider two gravitino mass regimes vastly separated, that is, m3/2=O(100) eV and m3/2≃100 GeV.

750 GeV Diphoton Excess from the Goldstino Superpartner [PDF]
Physical Review Letters, 2016 We interpret the di-photon excess recently reported by the ATLAS and CMS collaborations as a new resonance arising from the sgoldstino scalar, which is the superpartner of the Goldstone mode of spontaneous supersymmetry breaking, the goldstino. The sgoldstino is produced at the LHC via gluon fusion and decays to photons, with interaction strengths ...

Fluid super-dynamics from black hole superpartners [PDF]
Physics Letters B, 2011 Recently the Navier-Stokes equations have been derived from the duality with the black branes in AdS_5. The zero modes of black branes are reinterpreted as dynamical degrees of freedom of a conformal fluid on the boundary of AdS_5. Here, we derive the corrections to the Navier-Stokes equations due to fermionic zero modes of the black branes.

Higher spin supersymmetry at the cosmological collider: sculpting SUSY rilles in the CMB
Journal of High Energy Physics, 2019 We study the imprint of higher spin supermultiplets on cosmological correlators, namely the non-Gaussianity of the cosmic microwave background. Supersymmetry is used as a guide to introduce the contribution of fermionic higher spin particles, which have ...

High-Power Supersymmetric Semiconductor Laser with a Narrow Linewidth
Photonics, 2023 We have designed and fabricated a kind of supersymmetric slotted Fabry–Perot semiconductor laser near 1550 nm to achieve a single-mode, high-power, and narrow-linewidth operation.

, 2011 We explore an alternative mechanism for the production of gravitino dark matter whereby relic gravitinos originate from the decays of superpartners which are still in thermal equilibrium, i.e. via freeze-in.
