Fuzzy and Axion-Like Dark Matter as an Illusion

Authors: Sylwester Kornowski

Here we show that masses of dark-matter (DM) loops in the massive spiral galaxies have the same values as masses of the postulated fuzzy and axion-like DM particles. The DM loops are not fuzzy and, contrary to the spin-zero axion-like DM particles, spin of them is quantized. The DM loops in galactic halos interact with stars via the weak interactions of the virtual electron-positron pairs created spontaneously in spacetime. Such interactions decrease radii of the DM loops and simultaneously increase the orbital speeds of stars. We calculated also the small-scale cutoff for such loop-like DM.
