Recognizing superpartners at LEP [PDF]

open access: yesPhysics 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

open access: yesFortschritte 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

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.

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 ...

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.

Is the 125 GeV Higgs the superpartner of a neutrino? [PDF]

open access: yesJournal of High Energy Physics, 2013
Recent LHC searches have provided strong evidence for the Higgs, a boson whose gauge quantum numbers coincide with those of a SM fermion, the neutrino. This raises the mandatory question of whether Higgs and neutrino can be related by supersymmetry. We study this possibility in a model in which an approximate R-symmetry acts as a lepton number. We show

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 ...

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

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 ...
