Kination and the Inert Doublet Model
Geneviève Bélanger, Nicolás Bernal, Andreas Goudelis +1
The inert doublet model is a two-Higgs-doublet extension of the standard model that provides a minimal and versatile framework for frozen-out dark matter. Assuming standard cosmolo…
Probing the Phenomenology of Dark Matter from Decoupled Freeze-Out
Geneviève Bélanger, Aoife Bharucha, Sreemanti Chakraborti +2
We consider a model of dark matter where the mediator corresponds to a superposition of a scalar and pseudoscalar, and the scenario where, after reheating, the number densities of…
Illuminating Scalar Dark Matter Co-Scattering in EFT with Monophoton Signatures
Geneviève Bélanger, Manimala Mitra, Rojalin Padhan +1
We investigate the co-scattering mechanism for dark matter production in an EFT framework which contains new -odd singlets, namely two fermions and a real scalar …
Rekindling s-Wave Dark Matter Annihilation Below 10GeV with Breit-Wigner Effects
Geneviève Bélanger, Sreemanti Chakraborti, Cédric Delaunay +1
Velocity-independent (s-wave) annihilation of thermal Dark Matter is ruled out by CMB data for masses below 10GeV, effectively ruling out the possibility of indirectly detecting it…
-Mediated Dark Matter with Low-Temperature Reheating
Geneviève Bélanger, Nicolás Bernal, Alexander Pukhov
We consider a simple extension of the standard model with fermionic dark matter (DM) and a gauge boson acting as a mediator. We also assume a scenario where cosmic reheating o…
micrOMEGAs 6.0: N-component dark matter
G. Alguero, G. Belanger, F. Boudjema +5
micrOMEGAs is a numerical code to compute dark matter (DM) observables in generic extensions of the Standard Model of particle physics. We present a new version of micrOMEGAs that…
Physics with e^+e^- Linear Colliders
E. Accomando
We describe the physics potential of linear colliders in this report. These machines are planned to operate in the first phase at a center-of --mass energy of 500 GeV, bef…
