Supersymmetric localization: 𝒩 = (2, 2) theories on S2 and AdS2
Journal of High Energy Physics, 2023 Application of the supersymmetric localization method to theories on anti-de Sitter spacetime has received recent interest, yet still remains as a challenging problem. In this paper, we focus on (global) Euclidean AdS2, on which we consider an Abelian 𝒩 =

Supergravity with a Gravitino LSP [PDF]
, 2004 We investigate supergravity models in which the lightest supersymmetric particle (LSP) is a stable gravitino. We assume that the next-lightest supersymmetric particle (NLSP) freezes out with its thermal relic density before decaying to the gravitino at ...

T‐Symmetry in String Geometry Theory
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Analysis of Top Quark Pair Production Signal from Neutral 2HDM Higgs Bosons at LHC
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 In this paper, the top quark pair production events are analyzed as a source of neutral Higgs bosons of the two Higgs doublet model type I at LHC. The production mechanism is pp→H/A→tt¯ assuming a fully hadronic final state through t → Wb → jjb. In order to distinguish the signal from the main background which is the standard model tt¯, we benefit from

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 ...

N $$ \mathcal{N} $$ = 2 AdS4 supergravity, holography and Ward identities
Journal of High Energy Physics, 2021 We develop in detail the holographic framework for an N $$ \mathcal{N} $$ = 2 pure AdS supergravity model in four dimensions, including all the contributions from the fermionic fields and adopting the Fefferman-Graham parametrization.

ATLAS diboson excess from low scale supersymmetry breaking [PDF]
, 2015 We provide an interpretation of the recent ATLAS diboson excess in terms of a class of supersymmetric models in which the scale of supersymmetry (SUSY) breaking is in the few TeV range.

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar

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 ...

Fayet–Iliopoulos terms in supergravity and D-term inflation
European Physical Journal C: Particles and Fields, 2018 We analyse the consequences of a new gauge invariant Fayet–Iliopoulos (FI) term proposed recently to a class of inflation models driven by supersymmetry breaking with the inflaton being the superpartner of the goldstino. We first show that charged matter
