A bstract Motivated by the shift in experimental attention towards electroweak super-
symmetric particle production at the CERN LHC, we update in this paper our precision …

We explore the Higgs boson implications of a class of supersymmetric models, which
extends the MSSM gauge group by a U (1)′ symmetry, which is broken at low energy …

A bstract We test E 6 realisations of a generic U (1)′ extended Minimal Supersymmetric
Standard Model (UMSSM), parametrised in terms of the mixing angle pertaining to the new …

We perform a detailed analysis of dark matter signals of supersymmetric models containing
an extra U (1)′ gauge group. We investigate scenarios in which either the right sneutrino or …

A bstract We propose a simplified light higgsino-singlino scenario in the NMSSM, in which
the masses of the chargino and the lightest neutralino determine the masses and couplings …

We consider a class of U (1)′-extended minimal supersymmetric extension of the Standard
Model (MSSM) in which the U (1)′ symmetry is broken by vacuum expectation values of …

We perform a comprehensive analysis of the secluded supersymmetric U (1)′ model,
consistent with present experimental constraints. We find that, in this model, the additional …

We conduct a numerical study over the constrained MSSM (CMSSM), next-to-MSSM
(NMSSM) and U (1) extended MSSM (UMSSM) to probe the allowed mass ranges of the …

Abstract We study\(Z^{\prime}\) phenomenology at hadron colliders in an\(U (1)^{\prime}\)
extended MSSM. We choose a\(U (1)^{\prime}\) model with a secluded sector, where the …

We analyze the prospects for light neutralino dark matter in the minimal supersymmetric
model extended by a U (1) gauge group. We allow the neutralino to be an arbitrary …
