Scalar field dark matter and the Higgs field [PDF]

open access: diamondPhysics Letters B, 2016
We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be of the order of the Hubble parameter during inflation, as a result of its ...

Unified Dark Matter Scalar Field Models [PDF]

open access: greenAdvances in Astronomy, 2010
We analyze and review cosmological models in which the dynamics of a single scalar field accounts for a unified description of the Dark Matter and Dark Energy sectors, dubbed Unified Dark Matter (UDM) models.

Scale-invariant scalar field dark matter through the Higgs portal [PDF]

open access: diamondJournal of High Energy Physics, 2018
We discuss the dynamics and phenomenology of an oscillating scalar field coupled to the Higgs boson that accounts for the dark matter in the Universe. The model assumes an underlying scale invariance such that the scalar field only acquires mass after ...

Is Sextans dwarf galaxy in a scalar field dark matter halo? [PDF]

open access: bronze, 2014
The Bose-Einstein condensate/scalar field dark matter model, considers that the dark matter is composed by spinless-ultra-light particles which can be described by a scalar field.

Brief History of Ultra-light Scalar Dark Matter Models [PDF]

open access: yesEPJ Web of Conferences, 2018
This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion. In this model ultra-light scalar dark matter particles with mass m = O(10-22)eV condense

Short review of the main achievements of the scalar field, fuzzy, ultralight, wave, BEC dark matter model [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The Scalar Field Dark Matter model has been known in various ways throughout its history; Fuzzy, BEC, Wave, Ultralight, Axion-like Dark Matter, etc. All of them consist in proposing that dark matter of the universe is a spinless field Φ that follows the ...

Scalar field dark matter: helping or hurting small-scale problems in cosmology? [PDF]

open access: bronzeMonthly notices of the Royal Astronomical Society, 2018
Building upon results of cosmological simulations of ultra-light scalar field dark matter (SFDM), we present a comprehensive model for the density profiles of SFDM haloes as a function of halo virial mass $M_{\rm h}$ and scalar field mass $m$.

Core-envelope haloes in scalar field dark matter with repulsive self-interaction: fluid dynamics beyond the de Broglie wavelength [PDF]

open access: greenMonthly notices of the Royal Astronomical Society, 2021
Scalar Field Dark Matter (SFDM) comprised of ultralight bosons has attracted great interest as an alternative to standard, collisionless Cold Dark Matter (CDM) because of its novel structure-formation dynamics, described by the coupled Schrödinger ...

Scalar field dark matter with spontaneous symmetry breaking and the 3.5 keV line [PDF]

open access: yesPhysics Letters B, 2018
We show that the present dark matter abundance can be accounted for by an oscillating scalar field that acquires both mass and a non-zero expectation value from interactions with the Higgs field.
