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 ...

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.

Phenomenology of the utilitarian supersymmetric standard model
Nuclear Physics B, 2016 We study the 2010 specific version of the 2002 proposed U(1)X extension of the supersymmetric standard model, which has no μ term and conserves baryon number and lepton number separately and automatically.

Exceptional supersymmetric standard model [PDF]
Physics 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
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.

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

The supersymmetric standard model [PDF]
The European Physical Journal C, 2014 The Standard Model may be included within a supersymmetric theory, postulating new sparticles that differ by half-a-unit of spin from their standard model partners, and by a new quantum number called R-parity. The lightest one, usually a neutralino, is expected to be stable and a possible candidate for dark matter. The electroweak breaking requires two

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.
