Baryon-induced Collapse of Dark Matter Cores into Supermassive Black Holes
Articolo
Articolo
Nonlinear structure formation for fermionic dark matter particles leads to dark matter density profiles with a degenerate compact core surrounded by a diluted halo. For a given fermion mass, the core has a critical mass ...

Open AccessBoltzmann hierarchies for self-interacting warm dark matter scenarios
Articolo
Articolo
We provide a general framework for self-interacting warm dark matter (WDM) in cosmological perturbations, by deriving from first principles a Boltzmann hierarchy which retains certain independence from a particular inter...

Open AccessHiggsino-like dark matter from sneutrino late decays
Articolo
Articolo
We consider Higgsino-like dark matter (DM) in the Minimal Supersymmetric Standard Model (MSSM) with additional right-handed neutrino chiral superfields, and propose a new non-thermal way of generating the right amount of...

Open AccessMachine-learning performance on Higgs-pair production associated with dark matter at the LHC
Articolo
Articolo
Di-Higgs production at the LHC associated with missing transverse energy is explored in the context of simplified models that generically parameterize a large class of models with heavy scalars and dark matter candidates...

Open AccessOn the growth of supermassive black holes formed from the gravitational collapse of fermionic dark matter cores
Articolo
Articolo
Observations support the idea that supermassive black holes (SMBHs) power the emission at the centre of active galaxies. However, contrary to stellar-mass BHs, there is a poor understanding of their origin and physical f...

Open AccessTowards a method to anticipate dark matter signals with deep learning at the LHC
Articolo
Articolo
We study several simplified dark matter (DM) models and their signatures at the LHC using neural networks. We focus on the usual monojet plus missing transverse energy channel, but to train the algorithms we organize the...

Open AccessInteracting bosonic dark energy and fermionic dark matter in Einstein scalar Gauss–Bonnet gravity
Articolo
Articolo
Abstract We explore a cosmological framework in which a Gauss–Bonnet (GB) coupled scalar field, acting as dark energy, interacts with a fermionic dark matter field through a coupling obtained from the point of view of ...
