Noether-Wald charge in supergravity: the fermionic contribution

open access: yesJournal of High Energy Physics, 2023
We study the invariance of N $$ \mathcal{N} $$ = 1, d = 4 supergravity solutions under diffeormophisms and show that, in order to obtain consistent conditions (“Killing equations”) invariant under local supersymmetry transformations, one has to perform ...

Twisting D(2,1; α) Superspace

open access: yesFortschritte 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

Jenseits von Parität und Zeit

open access: yesPhysik 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

open access: yesAdvances 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.

Reheating after inflation by supersymmetry breaking

open access: yesEuropean 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,

Displaced lepton flavour violating signatures of right-handed sneutrinos in U(1)′ supersymmetric models

open access: yesJournal 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.

High-Power Supersymmetric Semiconductor Laser with a Narrow Linewidth

open access: yesPhotonics, 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.

Effective field theory approach to trans-TeV supersymmetry: covariant matching, Yukawa unification and Higgs couplings

open access: yesJournal of High Energy Physics, 2018
Dismissing traditional naturalness concerns while embracing the Higgs boson mass measurement and unification motivates careful analysis of trans-TeV supersymmetric theories.

Higher spin supersymmetry at the cosmological collider: sculpting SUSY rilles in the CMB

open access: yesJournal 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 ...

Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity

open access: yesJournal of High Energy Physics, 2018
We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infeld-type kinetic terms and a generalized (new) Fayet-Iliopoulos-type term ...
