Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity
Spencer Griffith, Juri Smirnov, Laura Lopez-Honorez +1
Minimal electroweak dark matter models are compelling due to their simplicity, though calculations of their freezeout abundance are complicated by nonperturbative effects due to So…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Dark matter from WIMP to FIMP over three regimes: Cosmology versus Colliders
Laura Lopez-Honorez, Quentin Decant, Sam Junius +1
Dark matter models can give rise to specific signatures at particle physics experiments or in cosmology. The details of the cosmological history can also influence the new physics…
Cosmological imprints of non-thermalized dark matter
Quentin Decant, Jan Heisig, Deanna C. Hooper +1
Non-thermalized dark matter is a cosmologically viable alternative to the widely studied weakly interacting massive particle. We study the evolution of the dark matter phase-space…
Displaced new physics at colliders and the early universe before its first second
Lorenzo Calibbi, Francesco D'Eramo, Sam Junius +2
Displaced vertices at colliders, arising from the production and decay of long-lived particles, probe dark matter candidates produced via freeze-in. If one assumes a standard cosmo…
Strong dynamics and dark matter: investigating a minimal setup
Benjamin Fuks, Federica Giacchino, Laura Lopez-Honorez +2
We discuss the phenomenology of a dark matter scenario in which we extend the Standard Model by a real scalar particle and a vector-like heavy quark. Such a model can be seen as a…
A feeble window on leptophilic dark matter
Sam Junius, Laura Lopez-Honorez, Alberto Mariotti
In this paper we study a leptophilic dark matter scenario involving feeble dark matter coupling to the Standard Model (SM) and compressed dark matter-mediator mass spectrum. We con…
Singlet-Doublet Dark Matter Freeze-in: LHC displaced signatures versus cosmology
Lorenzo Calibbi, Laura Lopez-Honorez, Steven Lowette +1
We study the Singlet-Doublet dark matter model in the regime of feeble couplings, where the dark matter abundance is obtained via the freeze-in mechanism. As a consequence of the s…
Dark Matter Constraints on Composite Higgs Models
Nayara Fonseca, Renata Zukanovich Funchal, Andre Lessa +1
In composite Higgs models the pseudo-Nambu-Goldstone Boson (pNGB) nature of the Higgs field is an interesting alternative for explaning the smallness of the electroweak scale with…
Bremsstrahlung and Gamma Ray Lines in 3 Scenarios of Dark Matter Annihilation
Federica Giacchino, Laura Lopez-Honorez, Michel H. G. Tytgat
Gamma ray spectral features are of interest for indirect searches of dark matter (DM). Following Barger et al, we consider 3 simple scenarios of DM that annihilates into Standard M…
Scalar Dark Matter Models with Significant Internal Bremsstrahlung
Federica Giacchino, Laura Lopez-Honorez, Michel H. G. Tytgat
There has been interest recently on particle physics models that may give rise to sharp gamma ray spectral features from dark matter annihilation. Because dark matter is supposed t…
Dark matter within the minimal flavour violation ansatz
Laura Lopez-Honorez, Luca Merlo
Minimal Flavour Violation hypothesis can provide an attractive framework for Dark Matter (DM). We consider scalar DM candidates carrying flavour quantum numbers and whose represent…
Status of the Inert Doublet Model and the Role of multileptons at the LHC
Michael Gustafsson, Sara Rydbeck, Laura Lopez-Honorez +1
A possible feature of the inert doublet model (IDM) is to provide a dark matter candidate together with an alteration of both direct and indirect collider constraints that allow fo…
Higgs portal, fermionic dark matter, and a Standard Model like Higgs at 125 GeV
Laura Lopez-Honorez, Thomas Schwetz, Jure Zupan
We show that fermionic dark matter (DM) which communicates with the Standard Model (SM) via the Higgs portal is a viable scenario, even if a SM-like Higgs is found at around 125 Ge…
A new viable region of the inert doublet model
Laura Lopez-Honorez, Carlos E. Yaguna
The inert doublet model, a minimal extension of the Standard Model by a second Higgs doublet, is one of the simplest and most attractive scenarios that can explain the dark matter.…
