A month-long observation of two horizontal ZnS(Ag) scintillating screens, 1 m^2 in area and located one above the other a certain distance apart, revealed about 10 correlated signals, whose time shift corresponds to an average velocity of…

Detection of daemons in low-background conditions in September 2005 and March 2006 has provided evidence for the expected to occur at that times maxima in the flux of daemons with V ~ 10-15 km s-1, which hit the Earth from near-Earth,…

Detection of negative daemons, DArk Electric Matter Objects, viz. Planckian supermassive (~2*10^-5 g) particles, whose population has been detected in March 2000 to populate near-Earth, almost circular, heliocentric orbits (NEACHOs), is…

Negative Dark Electric Matter Objects, daemons, have been detected by means of ZnS(Ag) scintillator screens. These objects are apparently relic elementary Planckian black holes. The scintillations in ZnS(Ag) are excited by electrons and…

The daemon-stimulated proton decay is capable of providing an appreciable part of the Sun luminosity as well as nonelectron flavor component in the solar neutrino flux. This follows (1) from our experiments on detection of negative daemons…

With a probability >99% there are grounds to believe that our works on detection of the Dark Electric Matter Objects (daemons), which were lauched in 1996, are crowned with success. The daemons are the relic elementary Planckian black…

During a week of the March maximum in 2011, two oppositely installed direction-sensitive TEU-167d Dark Electron Multipliers (DEMs) recorded a flux of daemons from the near-Earth almost circular heliocentric orbits (NEACHOs). The flux…

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…

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…

In 1997, we proposed a model of the ball lightning (BL) whose activity is accounted for by energy release in the fusion of light nuclei, most probably, carbon in organic fibers (Proc. ISBL 97, p.157). The fusion is provided by catalytic…

Detection of the September maximum in the primary near-Earth daemon flux at high (~60o) Northern latitudes by our set-up with a plane horizontal scintillator is plagued by purely geometric factors; indeed, because of the Earth's rotation…

The paper considers the fate of the electrically charged (Ze~10e) Planckian elementary black holes - daemons - making up the dark matter (DM) of the Galactic disk, which, as follows from our measurements, were trapped by the Earth during…

Despite strong evidence for the existence of large amounts of dark matter (DM) in our Universe, there is no direct indication of its presence in our own solar system. All estimates of the local DM density rely on extrapolating results on…

To constrain the properties of dark matter (DM) that interacts with nucleons, we have conducted an experimental search for any anomalous heating of ordinary baryonic matter at 77 K. Our tabletop experiment is motivated by the possibility…

Dark Matter in Earth intersecting orbits can scatter off the electrons and lose energy, and finally be gravitationally bound to Earth. Eventually they lose enough energy and accumulate at the core. It is assumed that DM annihilates/decays…

Strongly-interacting dark matter can be accumulated in large quantities inside the Earth, and for dark matter particles in a few GeV mass range, it can exist in large quantities near the Earth's surface. We investigate the constraints…

For dark matter (DM) particles with masses in the 0.6 - 6 m_p range, we set stringent constraints on the interaction cross-sections for scattering with ordinary baryonic matter. These constraints follow from the recognition that such…
