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.

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.

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 ...

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 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.

Gravitational waves from domain walls in the next-to-minimal supersymmetric standard model [PDF]
, 2015 The next-to-minimal supersymmetric standard model predicts the formation of domain walls due to the spontaneous breaking of the discrete Z3-symmetry at the electroweak phase transition, and they collapse before the epoch of big bang nucleosynthesis if ...

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

Z(2)-Singlino Dark Matter in a Portal-Like Extension of the Minimal Supersymmetric Standard Model. [PDF]
, 2008 We propose a Z2-stabilized singlino () as a dark matter candidate in extended and R-parity violating versions of the supersymmetric standard model. interacts with visible matter via a heavy messenger field S, which results in a supersymmetric version of ...
