Fortschritte der Physik, Volume 69, Issue 10, October 2021., 2021 Abstract We develop a three‐dimensional theory of rigid supersymmetry describing the dynamics of a set of hypermultiplets on a curved AdS3 worldvolume background, whose supersymmetry is captured by the supergroup . To unveil some remarkable features of this model, we perform two twists, involving the SL factors of the theory. After the first twist, our

Physik in unserer Zeit, Volume 52, Issue 1, Page 26-31, January 2021., 2021 Supersymmetrie ist durch die Teilchenphysik bekannt geworden. Seit Kurzem inspiriert das Konzept aus der Quantenfeldtheorie auch ein innovatives Design komplexer photonischer Bauelemente und Schaltkreise für die lichtgestützte Informationsverarbeitung.

Reparameterization Invariant Model of a Supersymmetric System: BRST and Supervariable Approaches
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We carry out the Becchi‐Rouet‐Stora‐Tyutin (BRST) quantization of the one (0 + 1)‐dimensional (1D) model of a free massive spinning relativistic particle (i.e., a supersymmetric system) by exploiting its classical infinitesimal and continuous reparameterization symmetry transformations.

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.

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.

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,

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.

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 ...
