Scalar field dark matter and the Higgs field [PDF]
Physics 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 ...

Short review of the main achievements of the scalar field, fuzzy, ultralight, wave, BEC dark matter model [PDF]
Frontiers 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 with spontaneous symmetry breaking and the 3.5 keV line [PDF]
Physics 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.

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

Brief Review on Scalar Field Dark Matter Models
Frontiers in Astronomy and Space Sciences, 2019 The existence of dark matter in the universe has been solidly established in the last decades, after the arrival of accurate cosmological and astrophysical observations, and some consider it the most challenging problem in modern physics.

Small scale structures in coupled scalar field dark matter [PDF]
Physics Letters B, 2014 We investigate structure formation for ultra-light scalar field dark matter coupled to quintessence, in particular the cosmon–bolon system. The linear power spectrum is computed by a numerical solution of the coupled field equations.

Searching for scalar field dark matter using cavity resonators and capacitors [PDF]
Physical Review D, 2022 We establish new experiments to search for dark matter based on a model of a light scalar field with a dilaton-like coupling to the electromagnetic field, which is strongly motivated by superstring theory.

Constraints on the mass and self-coupling of ultra-light scalar field dark matter using observational limits on galactic central mass [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 It is well known that Ultra-Light Dark Matter (ULDM), usually scalar fields of mass m ∼ 10-22 eV, can solve some of the outstanding problems of the Cold Dark Matter (CDM) paradigm. Such a scalar field could have non-negligible self-coupling λ.

Scalar field dark matter and dark energy: a hybrid model for the dark sector [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 Diverse cosmological and astrophysical observations strongly hint at the presence of dark matter and dark energy in the Universe. One of the main goals of Cosmology is to explain the nature of these two components.
