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 ...

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 ...

Sum rules in the superpartner spectrum of the minimal supersymmetric standard model [PDF]
Phys.Lett. B432 (1998) 108-113, 1997 Assuming that the string inspired, universal sum rules for soft supersymmetry-breaking terms, which have been recently found both in a wide class of four-dimensional superstrings and in supersymmertic gauge-Yukawa unified gauge models, are satisfied above and at the grand unification scale, we investigate theirlow energy consequences and derive sum ...

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 ...

Gravitino cosmology helped by a right handed (s)neutrino
Physics Letters B, 2022 In this paper, we discuss interesting scenarios resulting from the interplay between the gravitino and the lightest right-handed (s)neutrino. We consider two gravitino mass regimes vastly separated, that is, m3/2=O(100) eV and m3/2≃100 GeV.

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 ...

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 The QCD light‐front Hamiltonian equation HLF|Ψ〉 = M2|Ψ〉 derived from quantization at fixed LF time τ = t + z/c provides a causal, frame‐independent method for computing hadron spectroscopy as well as dynamical observables such as structure functions, transverse momentum distributions, and distribution amplitudes. The QCD Lagrangian with zero quark mass

LHC Signals of Pure Gravity Mediation
EPJ Web of Conferences, 2013 Evidence is mounting that natural supersymmetry at the weak scale is not realized in nature. This evidence comes from collider searches, a lack of new flavor changing neutral current effects, and now also the size of the measured Higgs mass. On the other

Supersymmetric $η$ operators [PDF]
, 2012 Being chosen as a differential operator of a special form, metric $\eta$ operator becomes unitary equivalent to a one-dimensional Hermitian Hamiltonian with a natural supersymmetric structure. We show that fixing the superpartner of this Hamiltonian permits to determine both the metric operator and corresponding non-Hermitian Hamiltonian.
