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 ...

Unified Dark Matter Scalar Field Models [PDF]
Advances 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.

Testing the mean field theory of scalar field dark matter
SciPost Physics Proceedings, 2023 Scalar field dark matter offers an interesting alternative to the traditional WIMP dark matter picture. Astrophysical and cosmological simulations are useful to constraining the mass of the dark matter particle in this model. This is particularly true at

Galactic collapse of scalar field dark matter [PDF]
Classical and Quantum Gravity, 2002 We present a scenario for galaxy formation based on the hypothesis of scalar field dark matter. We interpret galaxy formation through the collapse of a scalar field fluctuation. We find that a cosh potential for the self-interaction of the scalar field provides a reasonable scenario for galactic formation, which is in agreement with cosmological ...

Newtonian collapse of scalar field dark matter [PDF]
Physical Review D, 2003 In this letter, we develop a Newtonian approach to the collapse of galaxy fluctuations of scalar field dark matter under initial conditions inferred from simple assumptions. The full relativistic system, the so called Einstein-Klein-Gordon, is reduced to the Schr dinger-Newton one in the weak field limit. The scaling symmetries of the SN equations are

Oscillating scalar-field dark matter in supergravity [PDF]
Journal of High Energy Physics, 2001 We show that an oscillating scalar field in supergravity of mass of the order of $\sim$ TeV with a nonzero vacuum expectation value ($\sim 10^{10}$ GeV) can be a candidate of cold dark matter (CDM). To avoid the gravitino problem, we need a low reheating temperature after the primordial inflation.

Small scale structures in coupled scalar field dark matter
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.

Higgs particles interacting via a scalar Dark Matter field [PDF]
EPJ Web of Conferences, 2016 We study a system of two Higgs particles, interacting via a scalar Dark Matter mediating field. The variational method in the Hamiltonian formalism of QFT is used to derive relativistic wave equations for the two-Higgs system, using a truncated Fock ...
