Z′ Portal Dark Matter in the Minimal B − L Model
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We consider a dark matter scenario in the context of the minimal extension of the Standard Model (SM) with a B − L (baryon number minus lepton number) gauge symmetry, where three right‐handed neutrinos with a B − L charge −1 and a B − L Higgs field with a B − L charge +2 are introduced to make the model anomaly‐free and to break the B − L gauge ...

Supersymmetry with no superpartners
Physics Letters B, 1993 Abstract A gauge theory of left-handed supergravity and non-supersymmetric left-handed spin- 1 2 matter is obtained from a higher gauge symmetry which is based on a four-dimensional spacetime specified by (xμθαμ(x)), where θαμ(x) is a vector-spinor. The spacetime origin of parity violation is demonstrated.

Exploring compressed supersymmetry with same-sign top quarks at the Large Hadron Collider [PDF]
, 2008 In compressed supersymmetry, a light top squark naturally mediates efficient neutralino pair annihilation to govern the thermal relic abundance of dark matter.

Higgs Information and NMSSM at the Large Hadron Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.Information theory has proven to be a worthwhile tool for investigating the implications of the Higgs sector in the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) using Higgs information at the Large Hadron Collider (LHC) assessed through the entropy constructed by means of the branching ratios of decay channels of the Higgs boson.

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We construct two‐dimensional integrable and superintegrable systems in terms of the master function formalism and relate them to Mielnik’s and Marquette’s construction in supersymmetric quantum mechanics. For two different cases of the master functions, we obtain two different two‐dimensional superintegrable systems with higher order integrals of ...

750 GeV Diphoton Excess from the Goldstino Superpartner [PDF]
Physical Review Letters, 2016 We interpret the di-photon excess recently reported by the ATLAS and CMS collaborations as a new resonance arising from the sgoldstino scalar, which is the superpartner of the Goldstone mode of spontaneous supersymmetry breaking, the goldstino. The sgoldstino is produced at the LHC via gluon fusion and decays to photons, with interaction strengths ...

A Chargeless Complex Vector Matter Field in Supersymmetric Scenario
Advances in High Energy Physics, 2015 We construct and study a formulation of a chargeless complex vector matter field in a supersymmetric framework. To this aim we combine two nochiral scalar superfields in order to take the vector component field to build the chargeless complex vector ...

The Discreet Charm of Higgsino Dark Matter: A Pocket Review
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...

An R-parity conserving radiative neutrino mass model without right-handed neutrinos
, 2010 The model proposed by A. Zee (1986) and K.S. Babu (1988) is a simple radiative seesaw model, in which tiny neutrino masses are generated at the two-loop level.
