DARK MATTER INTERFERENCE [PDF]
Modern Physics Letters A, 2012 We study different patterns of interference in WIMP-nuclei elastic scattering that can accommodate the DAMA and CoGeNT experiments via an isospin violating ratio fn/fp = -0.71. We study interference between the following pairs of mediators: Z and Z′, Z′ and Higgs, and two Higgs fields. We show under what conditions interference works.

Dark matter from a dark connection [PDF]
Modern Physics Letters A, 2021 In the first part of this note, we observe that a non-Riemannian piece in the affine connection (a “dark connection”) leads to an algebraically determined, conserved, symmetric 2-tensor in the Einstein field equations that is a natural dark matter candidate. The only other effect it has, is through its coupling to standard model fermions via covariant

Physics Letters B, 2019 The paper brings a novel approach to unification of dark matter and dark energy in terms of a cosmic fluid. A model is introduced in which the cosmic fluid speed of sound squared is defined as a function of its equation of state (EoS) parameter. It is shown how logarithmic part of this function results in dynamical regimes previously not observed in ...

THE DARK-MATTER WORLD: ARE THERE DARK-MATTER GALAXIES? [PDF]
International Journal of Modern Physics: Conference Series, 2012 We attempt to answer whether neutrinos and antineutrinos, such as those in the cosmic neutrino background, would clusterize among themselves or even with other dark-matter particles, under certain time span, say 1 Gyr. With neutrino masses in place, the similarity with the ordinary matter increases and so is our confidence for neutrino clustering if ...

COMPOSITE DARK MATTER AND PUZZLES OF DARK MATTER SEARCHES [PDF]
International Journal of Modern Physics D, 2010 Positive results of dark matter searches in DAMA/ NaI and DAMA/LIBRA experiments, being put together with the results of other groups, can imply nontrivial particle physics solutions for cosmological dark matter. Stable particles with charge -2, bound with primordial helium in O -helium "atoms" ( OHe ), represent a specific warmer than cold nuclear ...

DARK MATTER, AND ITS DARKNESS [PDF]
International Journal of Modern Physics D, 2006 Assuming the validity of the general relativistic description of gravitation on astrophysical and cosmological length scales, we analytically infer that the Friedmann–Robertson–Walker cosmology with Einsteinian cosmological constant, and a vanishing spatial curvature constant, unambiguously requires a significant amount of dark matter.

International Journal of Modern Physics A, 2006 More than 90% of matter in the Universe could be composed of heavy particles, which were non-relativistic, or 'cold', when they froze-out from the primordial soup. I will review current searches for these hypothetical particles, both via interactions with nuclei in deep underground detectors, and via the observation of their annihilation products in ...
