Augury of Darkness: The Low-Mass Dark Z' Portal

Alexandre Alves, Giorgio Arcadi, Yann Mambrini +2

Dirac fermion dark matter models with heavy mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to…

Gravitino or Axino Dark Matter with Reheat Temperature as high as GeV

Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall

A new scheme for lightest supersymmetric particle (LSP) dark matter is introduced and studied in theories of TeV supersymmetry with a QCD axion, , and a high reheat temperature…

Explaining Dark Matter and Decay Anomalies with an Model

Wolfgang Altmannshofer, Stefania Gori, Stefano Profumo +1

We present a dark sector model based on gauging the symmetry that addresses anomalies in decays and that features a particle dark matter candid…

Alignment without Decoupling: the Portal to Light Dark Matter in the MSSM

Stefano Profumo, Tim Stefaniak

We study light, thermal neutralino dark matter in the sub-GeV to 65 GeV mass range in the Minimal Supersymmetric extension of the Standard Model (MSSM). We consider realizations of…

The Light and Heavy Higgs Interpretation of the MSSM

Philip Bechtle, Howard E. Haber, Sven Heinemeyer +4

We perform a parameter scan of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with eight parameters taking into account the experimental Higgs boson results fro…

Partially Natural Two Higgs Doublet Models

Patrick Draper, Howard E. Haber, Joshua T. Ruderman

It is possible that the electroweak scale is low due to the fine-tuning of microscopic parameters, which can result from selection effects. The experimental discovery of new light…

You can hide but you have to run: direct detection with vector mediators

Francesco D'Eramo, Bradley J. Kavanagh, Paolo Panci

We study direct detection in simplified models of Dark Matter (DM) in which interactions with Standard Model (SM) fermions are mediated by a heavy vector boson. We consider fully g…

Dark Matter Inelastic Up-Scattering with the Interstellar Plasma: An Exciting New Source of X-Ray Lines, including at 3.5 keV

Francesco D'Eramo, Kevin Hambleton, Stefano Profumo +1

We explore the phenomenology of a class of models where the dark matter particle can inelastically up-scatter to a heavier excited state via off-diagonal dipolar interactions with…

SaxiGUTs and their Predictions

Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall

We introduce a class of unified supersymmetric axion theories with unified and PQ symmetries broken by the same set of fields at a scale GeV. A typical domai…

A White Paper on keV Sterile Neutrino Dark Matter

R. Adhikari, M. Agostini, N. Anh Ky +133

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…

LHC Benchmark Scenarios for the Real Higgs Singlet Extension of the Standard Model

Tania Robens, Tim Stefaniak

We present benchmark scenarios for searches for an additional Higgs state in the real Higgs singlet extension of the Standard Model in Run 2 of the LHC. The scenarios are selected…

A 750 GeV Portal: LHC Phenomenology and Dark Matter Candidates

Francesco D'Eramo, Jordy de Vries, Paolo Panci

We study the effective field theory obtained by extending the Standard Model field content with two singlets: a 750 GeV (pseudo-)scalar and a stable fermion. Accounting for collide…
