Exact Local Supersymmetry, Absence of Superpartners, and Noncommutative Geometries [PDF]
, 1997 It is pointed out that if we allow for the possibility of a multilayered universe, it is possible to maintain exact supersymmetry and arrange, in principle, for the vanishing of the cosmological constant. Superpartner(s) of a known particle will then be associated with the other layers of such a universe.

LIGHT SUPERPARTNERS AT HADRON COLLIDERS [PDF]
International Journal of Modern Physics A, 2006 Uncertainties of the MSSM predictions are due to an unknown SUSY breaking mechanism. To reduce these uncertainties, one usually imposes constraints on the MSSM parameter space. Recently, two new constraints became available, both from astrophysics: WMAP precise measurement of the amount of the Dark Matter in the Universe and EGRET data on an excess in

Lepto-axiogenesis and the scale of supersymmetry
Journal of High Energy Physics, 2023 If the Peccei-Quinn field containing the QCD axion undergoes rotations in the early universe, the dimension-five operator responsible for neutrino masses can generate a lepton asymmetry that ultimately gives rise to the observed baryon asymmetry of the ...

Supersymmetric Reshaping and Higher‐Dimensional Rearrangement of Photonic Lattices
Laser &Photonics Reviews, Volume 17, Issue 10, October 2023., 2023 Self‐imaging Jx photonic lattices enable perfect transfer of quantum and classical states, yet are challenging to implement at scale. In this paper, supersymmetry is harnessed to construct 2D systems with spectra identical to that of 1D Jx lattices that retain their key imaging and state transfer properties, while requiring dramatically fewer distinct ...

Recognizing Superpartners at LEP [PDF]
Physics Letters B, 1997 There is a class of supersymmetric models which is well-motivated by hints of evidence for SUSY and consistent with all existing data. It is important to study the predictions of these models. They are characterized by M(N3) > M(C1) > M(snu) > M(N1) (where Ni and Ci are neutralino and chargino mass eigenstates), |mu| ~< M1 ~< M2 ~= M(Z),

On the BPS Sector in AdS3/CFT2 Holography
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The BPS sector in AdS3/CFT2$AdS_3/CFT_2$ duality has been fertile ground for the exploration of gauge/gravity duality, from the match between black hole entropy and the CFT elliptic genus to the construction of large families of geometrical microstates and the identification of the corresponding states in the CFT.

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

Noether-Wald charge in supergravity: the fermionic contribution
Journal 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 ...
