Nonrelativistic supersymmetry in noncommutative space
(Elsevier Science, 2005-12)
We analyze a model of nonrelativistic matter in (2+1)-dimensional noncommutative space. The matter fields interact with gauge fields whose dynamics is dictated by a Chern-Simons term. We show that it is possible to choose ...
L ∞ algebras and tensor hierarchies in Exceptional Field Theory and Gauged Supergravity
(Springer, 2019-01)
We show how the gauge and field structure of the tensor hierarchies in Double and E7(7) Exceptional Field Theory fits into L∞ algebras. Special attention is paid to redefinitions, the role of covariantly constrained fields ...
MeV-GeV γ-ray telescopes probing gravitino LSP with coexisting axino NLSP as dark matter in the μνSSM
(Elsevier Science, 2021-02)
In R-parity violating supersymmetry, the gravitino as the lightest supersymmetric particle (LSP) is a good candidate for dark matter, with the interesting characteristic to be detectable through γ-ray telescopes. We extend ...
Hunting physics beyond the standard model with unusual W± and Z decays
(American Physical Society, 2015-02)
Nonstandard on-shell decays of W± and Z bosons are possible within the framework of extended supersymmetric models, i.e., with singlet states and/or new couplings compared to the minimal supersymmetric standard model. These ...
Discriminating between SUSY and non-SUSY Higgs sectors through the ratio H→ bb¯ / H→ τ+τ- with a 125 GeV Higgs boson
(Springer, 2016-05)
It is still an open question whether the new scalar particle discovered at the LHC with a mass of 125 GeV is the SM Higgs boson or belongs to models of new physics with an extended Higgs sector, as the MSSM or 2HDM. The ...
Search for supersymmetry at s√=8 TeV in final states with jets and two same-sign leptons or three leptons with the ATLAS detector
(Springer, 2014-04)
A search for strongly produced supersymmetric particles is conducted using signatures involving multiple energetic jets and either two isolated leptons (e or μ) with the same electric charge, or at least three isolated ...
Quaternionic structures, supertwistors and fundamental superspaces
(World Scientific, 2016-10)
Superspace is considered as space of parameters of the supercoherent states defining the basis for oscillator-like unitary irreducible representations of the generalized superconformal group SU(2m, 2n | 2N) in the field ...
Dynamical breaking of symmetries beyond the standard model and supergeometry
(IOP Publishing, 2019-09-26)
Group theoretical realizations containing the electroweak sector of the Standard Model (SM) are discussed from the supersymmetry point of view. Dynamical breaking of the symmetry is performed and the corresponding quadratic ...
Searches for electroweak production of supersymmetric particles with compressed mass spectra in √ s = 13 TeV p p collisions with the ATLAS detector
(American Physical Society, 2020-03)
This paper presents results of searches for the electroweak production of supersymmetric particles in models with compressed mass spectra. The searches use 139 fb−1 of √s=13 TeV proton-proton collision data collected by ...
Search for pair-produced third-generation squarks decaying via charm quarks or in compressed supersymmetric scenarios in pp collisions at s√=8 TeV with the ATLAS detector
(American Physical Society, 2014-09)
Results of a search for supersymmetry via direct production of third-generation squarks are reported, using 20.3 fb−1 of proton-proton collision data at s√=8 TeV recorded by the ATLAS experiment at the LHC in 2012. Two ...
