Dark Matter Freeze-in Production in Fast-Expanding Universes
Francesco D'Eramo, Nicolas Fernandez, Stefano Profumo
If the dark matter is produced in the early universe prior to Big Bang nucleosynthesis, a modified cosmological history can drastically affect the abundance of relic dark matter pa…
Supersymmetric Theory and Models
Howard E. Haber, Laurel Stephenson Haskins
In these introductory lectures, we review the theoretical tools used in constructing supersymmetric field theories and their application to physical models. We first introduce the…
Searching for Secluded Dark Matter with H.E.S.S., Fermi-LAT, and Planck
Stefano Profumo, Farinaldo S. Queiroz, Joseph Silk +1
Short-lived mediators are often used to describe dark matter interactions with Standard Model particles. When the dark matter mass is heavier than the mass of the mediator, it may…
Multi-Higgs doublet models: physical parametrization, sum rules and unitarity bounds
Miguel P. Bento, Howard E. Haber, J. C. Romão +1
If the scalar sector of the Standard Model is non-minimal, one might expect multiple generations of the hypercharge-1/2 scalar doublet analogous to the generational structure of th…
The Impact of Two-Loop Effects on the Scenario of MSSM Higgs Alignment without Decoupling
Howard E. Haber, Sven Heinemeyer, Tim Stefaniak
In multi-Higgs models, the properties of one neutral scalar state approximate those of the Standard Model (SM) Higgs boson in a limit where the corresponding scalar field is roughl…
The Not-So-Well Tempered Neutralino
Stefano Profumo, Tim Stefaniak, Laurel Stephenson Haskins
Light electroweakinos, the neutral and charged fermionic supersymmetric partners of the Standard Model gauge bosons and of the two $\mathrm{SU}(…
Status of the Charged Higgs Boson in Two Higgs Doublet Models
A. Arbey, F. Mahmoudi, O. Stal +1
The existence of charged Higgs boson(s) is inevitable in models with two (or more) Higgs doublets. Hence, their discovery would constitute unambiguous evidence for new physics beyo…
Surprises from Complete Vector Portal Theories: New Insights into the Dark Sector and its Interplay with Higgs Physics
Yanou Cui, Francesco D'Eramo
We study UV complete theories where the Standard Model (SM) gauge group is extended with a new abelian , and the field content is augmented by an arbitrary number of scalar a…
Axions, Instantons, and the Lattice
Michael Dine, Patrick Draper, Laurel Stephenson-Haskins +1
If the QCD axion is a significant component of dark matter, and if the universe was once hotter than a few hundred MeV, the axion relic abundance depends on the function , th…
Saxion Cosmology for Thermalized Gravitino Dark Matter
Raymond T. Co, Francesco D'Eramo, Lawrence J. Hall +1
In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium,…
The Waning of the WIMP? A Review of Models, Searches, and Constraints
Giorgio Arcadi, Maíra Dutra, Pradipta Ghosh +5
Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark matter candidates. In light of no conclusive detection signal yet despite an extensive search program…
When the Universe Expands Too Fast: Relentless Dark Matter
Francesco D'Eramo, Nicolas Fernandez, Stefano Profumo
We consider a modification to the standard cosmological history consisting of introducing a new species whose energy density red-shifts with the scale factor like $ρ_ϕ\prop…
High scale flavor alignment in two-Higgs doublet models and its phenomenology
Stefania Gori, Howard E. Haber, Edward Santos
The most general two-Higgs doublet model (2HDM) includes potentially large sources of flavor changing neutral currents (FCNCs) that must be suppressed in order to achieve a phenome…
Probing Leptophilic Dark Sectors with Hadronic Processes
Francesco D'Eramo, Bradley J. Kavanagh, Paolo Panci
We study vector portal dark matter models where the mediator couples only to leptons. In spite of the lack of tree-level couplings to colored states, radiative effects generate int…
