Dark Electric Matter Objects: History of Discovery, Modes of Interaction with Matter, Some Inferences and Prospects

Experiments with thin ZnS(Ag) scintillators provide evidence with C.L. > 99.99% for the existence of DArk Electric Matter Objects - daemons (presumably negatively charged Planckian particles with M ~ 10^-5 g) captured from the Galactic disk into near-Earth, almost circular heliocentric orbits. Their flux at V ~ 10-15 km/s was found to be as high as f > 10^-7 cm^-2 s^-1 and vary with P = 0.5 y, with maxima in March and September. A daemon flux f ~ 10^-7 - 10^-6 cm^-2 s^-1 is capable of accounting for the Troitsk anomaly in the tritium beta-spectrum and suggests its more pronounced manifestation in future KATRIN experiment. In view of the channeling effect on iodine recoil nuclei in the NaI(Tl) crystal, the DAMA/NaI experiment is also apparently detecting a flux of daemons, f ~ 6x10^-7 cm^-2 s^-1, but in this case of those falling with V = 30-50 km/s from strongly elongated, Earth-crossing heliocentric orbits oriented in the antapex direction, as a result of which the number of events detected in the 2-6-keV interval varies with P = 1 y.Comment: The invited talk at the "Sixth International Heidelberg Conference on Dark Matter in Astro and Particle Physics (DARK-2007)" (Sydney, Australia, 23-28 September, 2007; http://www.physics.usyd.edu.au/dark2007/Progr-Dark2007.html), 12 pages,including 3 figure

Daemons and DAMA: Their Celestial-Mechanics Interrelations

The assumption of the capture by the Solar System of the electrically charged Planckian DM objects (daemons) from the galactic disk is confirmed not only by the St.Petersburg (SPb) experiments detecting particles with V<30 km/s. Here the daemon approach is analyzed considering the positive model independent result of the DAMA/NaI experiment. We explain the maximum in DAMA signals observed in the May-June period to be 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 through ~90 deg 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 many times the Earth's orbit 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 ~1e-19 cm2 for the cross section of daemon interaction with the solar matter.Comment: 12 pages including 5 figure

Single-hit criterion in DAMA/LIBRA DM search and daemons - they are anything but weakly interacting

Our prediction that the more massive DAMA/LIBRA detector would detect a smaller number of events per unit of mass and time than the DAMA/NaI system has got confirmation. This is easy to understand, because DM objects are by far not the WIMPs of the Galactic halo that interact only weakly with matter but are apparently instead electrically charged Planckian objects, i.e., daemons which fall from Earth-crossing orbits with V = 30-50 km/s and undergo multiple interaction with condensed matter already in its outer layers, on a path of a few tens of cm. Therefore, one should use not compact massive detectors but rather systems with a large surface area, as we did to detect daemons with thin ZnS(Ag) scintillators. There are grounds to believe that correct use of the single-hit criterion in LIBRA should reveal DM particles with V = 30-50 km/s, and subsequently, with V = 10-15 km/s as well.Comment: 8 page
