Who's Afraid of the Supersymmetric Dark? The Standard Model vs Low‐Energy Supergravity

open access: yesFortschritte der Physik, Volume 70, Issue 7-8, August 2022., 2022
Abstract Use of supergravity equations in astronomy and late‐universe cosmology is often criticized on three grounds: (i) phenomenological success usually depends on the supergravity form for the scalar potential applying at the relevant energies; (ii$ii$) the low‐energy scalar potential is extremely sensitive to quantum effects involving very massive ...

Quintessence and the Swampland: The Numerically Controlled Regime of Moduli Space

open access: yesFortschritte der Physik, Volume 70, Issue 4, April 2022., 2022
Abstract We provide a detailed discussion of the main theoretical and phenomenological challenges of quintessence model building in any numerically controlled regime of the moduli space of string theory. We argue that a working quintessence model requires a leading order non‐supersymmetric (near) Minkowski vacuum with an axionic flat direction.

The anomaly that was not meant IIB

open access: yesFortschritte der Physik, Volume 70, Issue 1, January 2022., 2022
Abstract Type IIB supergravity enjoys a discrete non‐Abelian duality group, which has potential quantum anomalies. In this paper we explicitly compute these, and present the bordism group that controls them, modulo some physically motivated assumptions.

Discovery and Exclusion Prospects for Staus Produced by Heavy Higgs Boson Decays at the LHC

open access: yesAdvances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In a previous work, we developed a search strategy for staus produced by the decay of the heavy CP‐even Higgs boson H within the context of the large tanβ regime of the minimal supersymmetric standard model (MSSM) in a scenario of large stau mixing. Here, we study the performance of such search strategy by confronting it with the complementary mixing ...

New constraints on superpartner masses [PDF]

open access: yesPhysics Letters B, 1996
We consider the Minimal Supersymmetric Standard Model (MSSM) without imposing relations on the superpartner masses that arise in grand unified theories. Given an arbitrary pattern of superpartner masses (consistent with experimental constraints), it may happen that the scalar potential is actually unstable, even though all scalar masses-squared are ...

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

A Spin-1 Top Quark Superpartner [PDF]

open access: yesPhysical Review Letters, 2008
We construct a supersymmetric model where the left-handed top and bottom quarks are mainly the gauginos of a vector supermultiplet and hence their superpartners are spin-1. The right-handed top quark is unified with the Higgs, the top Yukawa arises from the gaugino coupling.

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.
