Daemons: Detection at Pulkovo, Gran Sasso, and Soudan

TL;DR

This paper reports the detection of daemons, hypothesized dark matter particles, using specialized detectors at Pulkovo, Gran Sasso, and Soudan, and interprets experimental data within the daemon paradigm to explain signals in dark matter detection experiments.

Contribution

It introduces a daemon detection method and provides a quantitative interpretation of DAMA and CoGeNT experimental results without additional hypotheses.

Findings

Detected daemon flux from near-Earth orbits with specific flux values.

Reinterpreted DAMA and CoGeNT signals as caused by daemons rather than WIMPs.

Suggested processing improvements for dark matter detection experiments.

Abstract

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 measured from above is f \approx (8\pm3)\times10^-7 cm^-2 s^-1, and that from below is twice smaller. The difference may be due both to specific design features of the TEUs themselves, and to dissimilarities in the slope of trajectories along which objects are coming from above or from below. It is shown that the daemon paradigm enables a quantitative interpretation of DAMA and CoGeNT experiments with no additional hypotheses. Both the experiments record a daemon flux of f ~ 10^-6 cm^-2 s^-1 from strongly elongated Earth-crossing heliocentric orbits (SEECHOs), predecessors of NEACHOs. Recommendations are given for processing of DAMA/LIBRA data, which unambiguously suggest that, in approximately half of cases (when there occur double events in the detector, rejected in processing under a single-hit criterion), the signals being recorded are successively excited by a single SEECHO object along a path of ~1 m, i.e., this is not a WIMP. It is noted that due regard to cascade events and pair interaction of ions will weaken the adverse influence exerted by the blocking effect on the channeling of iodine ions knocked out in NaI(Tl) crystal. This influence will become not so catastrophic as it follows from simplified semi-analytical models of the process: one might expect the energy of up to ~10% of primary recoil iodine ions will be converted to the scintillation light.
