Physics Letters B, 2020 In this paper, we consider a generic hidden sector which interacts only gravitationally with Standard Model particles. We show that quantum gravity leads to operators which can be probed with fifth force type experiments.

Dwarf galaxies in multistate scalar field dark matter halos [PDF]
, 2014 We analyse the velocity dispersion for eight of the Milky Way dwarf spheroidalsatellites in the context of finite temperature scalar field dark mater.

Journal of High Energy Physics, 2021 We propose a new mechanism to communicate between fermion dark matter and the Standard Model (SM) only through the four-form flux. The four-form couplings are responsible for the relaxation of the Higgs mass to the correct value and the initial ...

EVOLUTION OF A DWARF SATELLITE GALAXY EMBEDDED IN A SCALAR FIELD DARK MATTER HALO [PDF]
, 2014 The cold dark matter (CDM) model has two unsolved issues: simulations overpredict the satellite abundance around the Milky Way (MW) and it disagrees with observations of the central densities of dwarf galaxies which prefer constant density (core ...

Lepton-flavoured scalar dark matter in Dark Minimal Flavour Violation
Journal of High Energy Physics, 2023 We study a simplified model of lepton-flavoured complex scalar dark matter set up in the Dark Minimal Flavour Violation framework. In this model the Standard Model is extended by a scalar dark matter flavour triplet and a charged fermionic mediator ...

Spontaneous electro-weak symmetry breaking and cold dark matter
, 2006 In the standard model, the weak gauge bosons and fermions obtain mass after spontaneous electro-weak symmetry breaking, which is realized through one fundamental scalar field, namely Higgs field.

Scalar field dark matter mass model and evolution of rotation curves for low surface brightness galaxies [PDF]
, 2014 We study the evolution of gas rotation curves within the scalar field dark matter (SFDM) model. In this model, the galactic haloes are astronomical Bose–Einstein condensate drops of scalar field (SF).

One-loop quantum corrections to cosmological scalar field potentials
, 2007 We study the loop corrections to potentials of complex or coupled real scalar fields used in cosmology to account for dark energy, dark matter or dark fluid.

Model for a Universe described by a non-minimally coupled scalar field and interacting dark matter
, 2006 In this work it is investigated the evolution of a Universe where a scalar field, non-minimally coupled to space-time curvature, plays the role of quintessence and drives the Universe to a present accelerated expansion.
