Abnormal particles whose origin remains inexplicable

Abnormal particles whose origin remains inexplicable 1

An international team of scientists has detected abnormal particles whose origin remains inexplicable. The discovery, which can refute modern ideas about particle physics, is reported in a preprint published in the repository .

Researchers have discovered several neutrino candidates using ANITA atmospheric probes (Antarctic Impulsive Transient Antenna). Two of the three events, which are interpreted as tau neutrinos, turned out to be associated with the atmospheric shower of high-energy particles that arose during the interaction of the Earth’s atmosphere with tau leptons. The latter flew out of the core of the Earth, with which tau neutrinos interacted, which came from the other side of the planet.

The third possible neutrino was found during the search for the Askaryan effect – radiation that occurs when particles at light speeds pass through the Earth’s substance. However, scientists also did not exclude that this event is associated with background radiation.

Physicists tested the hypothesis that all recorded neutrinos were of cosmic origin and originated in natural accelerators (for example, blazars). In this case, a secondary stream of low-energy neutrinos should have arisen, to which IceCube detectors with certain characteristics are sensitive. The data collected by the under-ice neutrino observatory over seven years were analyzed, but no signs of such a flow were found.

High-energy neutrinos were first detected by IceCube detectors in 2013. It is believed that part of these particles is born from the interaction of cosmic rays and matter (or radiation fields) in the vicinity of natural cosmic accelerators. Another type of high-energy neutrino occurs when cosmic rays interact with the cosmic microwave background. These particles pass through the Earth from all directions in a uniform flow.

According to scientists, the origin of the recorded neutrino candidates cannot be explained within the Standard Model. In the case of a uniform flow, ANITA was supposed to record similar events from different viewing angles. No possible neutrino source was also found in the direction for the neutrino candidate resulting from the proposed Askarian effect. However, these anomalies can be explained by new physics, which suggests the presence of axionic and heavy dark matter, sterile neutrinos, and supersymmetries.
