Daemons and DAMA: Their celestial–mechanics interrelations

Abstract

The assumption of the capture by the Solar System of electrically charged Planckian DM objects (daemons) from the galactic disk is confirmed by the St Petersburg (SPb) experiments detecting particles with V < 30 km/s. Here the daemon approach is analysed considering the positive model independent results of the DAMA/NaI experiment in Gran Sasso. The maximum in DAMA signals observed in the May–June period is explained as being associated with the formation behind the Sun of a trail of daemons that the Sun captures into elongated orbits as it moves to the apex. The range of significant 2–6-keV DAMA signals fits well the iodine nuclei elastically knocked out of the NaI(Tl) scintillator by particles falling on the Earth with V = 30−50 km/s from strongly elongated heliocentric orbits. The half-year periodicity of the slower daemons observed in SPb originates from the transfer of particles, that are deflected by the Sun through ∼90°, into near-Earth orbits each time the particles cross the outer reaches of the Sun which had captured them. Their multi-loop (cross-like) trajectories traverse the Earth's orbit many times in March and September, which increases the probability for the particles to enter near-Earth orbits during this time. Corroboration of celestial mechanics calculations with observations yields ∼10⁻¹⁹ cm² for the cross-section of daemon interaction with the solar matter.
