Who's Afraid of the Supersymmetric Dark? The Standard Model vs Low‐Energy Supergravity [PDF]

open access: yesFortschritte der Physik, 2021
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 ...

Hunting wino and higgsino dark matter at the muon collider with disappearing tracks

open access: yesJournal 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

Anomalous muon magnetic moment in the inverse seesaw extended next-to-minimal supersymmetric standard model [PDF]

open access: yesPhysical Review D, 2019
The present work investigates the possibility that both dark matter and the anomalous magnetic moment of the muon may be explained within the context of the inverse seesaw extended next-to-minimal supersymmetric Standard Model (ISS-NMSSM).

Exceptional supersymmetric standard model [PDF]

open access: yesPhysics Letters B, 2006
We discuss some phenomenological aspects of an $E_6$ inspired supersymmetric standard model with an extra $U(1)_{N}$ gauge symmetry under which right-handed neutrinos have zero charge, allowing a conventional see-saw mechanism. The $ $ problem is solved in a similar way to the NMSSM, but without the accompanying problems of singlet tadpoles or domain ...

Lepton flavor violating decays τ → Pl in the U(1) X SSM model

open access: yesJournal 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.

Uncertainties in the lightest $$CP$$CP even Higgs boson mass prediction in the minimal supersymmetric standard model: fixed order versus effective field theory prediction [PDF]

open access: yesThe European Physical Journal C, 2018
We quantify and examine the uncertainties in predictions of the lightest $$CP$$CP even Higgs boson pole mass $$M_h$$Mh in the Minimal Supersymmetric Standard Model ($${\text {MSSM}}$$MSSM), utilising current spectrum generators and including some three ...

The standard model partly supersymmetric [PDF]

open access: yesPhysical 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.

No-scale supersymmetric standard model [PDF]

open access: yesPhysics 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 ...

750 GeV diphoton resonance from singlets in an exceptional supersymmetric standard model [PDF]

open access: yesJournal 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.
