Linking the supersymmetric standard model to the cosmological constant [PDF]
Journal of High Energy Physics, 2021 String theory has no parameter except the string scale M S , so the Planck scale M Pl, the supersymmetry-breaking scale , the electroweak scale m EW as well as the vacuum energy density (cosmological constant) Λ are to be determined dynamically at any ...

A 125 GeV Higgs and Its Diphoton Signal in Different SUSY Models: A Mini Review [PDF]
Advances in High Energy Physics, 2012 In this paper we briefly review our recent studies on a 125 GeV Higgs and its diphoton signal rate in different low-energy supersymmetric models, namely, the minimal supersymmetric standard model (MSSM), the next-to-minimal supersymmetric standard model (

Soft supersymmetry breaking and the supersymmetric standard model [PDF]
, 2001 We recall how the idea of Softly Broken Supersymmetry led to the construction of the Supersymmetric Standard Model in 1981. Its first prediction, the supersymmetric unification of gauge couplings, was conclusively verified by the LEP and SLC experiments ...

Hunting wino and higgsino dark matter at the muon collider with disappearing tracks
Journal of High Energy Physics, 2021 We study the capabilities of a muon collider experiment to detect disappearing tracks originating when a heavy and electrically charged long-lived particle decays via X + → Y + Z 0, where X + and Z 0 are two almost mass degenerate new states and Y + is a

Lepton flavor violating decays τ → Pl in the U(1) X SSM model
Journal of High Energy Physics, 2022 U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM.

Constraining new physics with SModelS version 2
Journal of High Energy Physics, 2022 We present version 2 of SModelS, a program package for the fast reinterpretation of LHC searches for new physics on the basis of simplified model results.

A long-lived stop with freeze-in and freeze-out dark matter in the hidden sector
Journal of High Energy Physics, 2020 In extended supersymmetric models with a hidden sector the lightest R-parity odd particle can reside in the hidden sector and act as dark matter. We consider the case when the hidden sector has ultraweak interactions with the visible sector.

Searching for the Higgsino-Bino sector at the LHC
Journal of High Energy Physics, 2020 We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...

Supersymmetric preons and the standard model
Nuclear Physics B, 2018 The experimental fact that standard model superpartners have not been observed compels one to consider an alternative implementation for supersymmetry.

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel
Journal of High Energy Physics, 2018 We examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model.
