The standard model partly supersymmetric [PDF]
Physical Review D, 2003 We present a novel class of theories where supersymmetry is only preserved in a partial (non-isolated) sector. The supersymmetric sector consists of CFT bound-states that can coexist with fundamental states which do not respect supersymmetry.

750 GeV diphoton resonance from singlets in an exceptional supersymmetric standard model [PDF]
Journal of High Energy Physics, 2016 The 750-760 GeV diphoton resonance may be identified as one or two scalars and/or one or two pseudoscalars contained in the two singlet superfields S1,2 arising from the three 27-dimensional representations of E6.

Bubbles in the supersymmetric standard model [PDF]
Nuclear Physics B, 1998 We compute the tunneling probability from the symmetric phase to the true vacuum, in the first order electroweak phase transition of the MSSM, and the corresponding Higgs profiles along the bubble wall. We use the resummed two-loop temperature-dependent effective potential, and pay particular attention to the light stop scenario, where the phase ...

Stop Co-Annihilation in the Minimal Supersymmetric Standard Model Revisited [PDF]
, 2017 We reexamine the stop co-annihilation scenario of the minimal supersymmetric standard model, wherein a binolike lightest supersymmetric particle has a thermal relic density set by co-annihilations with a scalar partner of the top quark in the early ...

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.

Search for Mono-Higgs signals at the LHC in the B-L supersymmetric standard model [PDF]
, 2016 We study mono-Higgs signatures emerging in the $B\ensuremath{-}L$ supersymmetric standard model induced by new channels not present in the minimal supersymmetric standard model, i.e., via topologies in which the mediator is either a heavy ${Z ...

No-scale supersymmetric standard model [PDF]
Physics Letters B, 1984 Abstract We propose a class of supergravity models coupled to matter in which the scales of supersymmetry breaking and of weak gauge symmetry breaking are both fixed by dimensional transmutation, not put in by hand. The models have a flat potential with zero cosmological constant before the evaluation of weak radiative corrections which determine ...

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.

New physics explanations of a μ in light of the FNAL muon g − 2 measurement
Journal of High Energy Physics, 2021 The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world average deviation ∆ a ...

A description of the Galactic Center excess in the Minimal Supersymmetric Standard Model [PDF]
, 2015 Observations with the Fermi Large Area Telescope (LAT) indicate an excess in gamma rays originating from the center of our Galaxy. A possible explanation for this excess is the annihilation of Dark Matter particles.
