Images of single atoms can help look for neutral double beta decay

The team of international physicists has developed a new technique to detect a hypothetical process called Double Beta Decay Neutral. Their techniques include checking large samples of xenon for the nucleus produced by the decay process. Recognizing the neutral

double beta decay can have a profound impact on our understanding of the universe.

The central topic in particle physics is whether neutrinos are their own antiparticles. If so, there should be a double neutron beta decay – which is prohibited in standard particle physics models. Therefore, several trials have competed to recognize or exclude this exotic decay, which is very rare.

Beta degradation involves a set of processes in which neutrinos (or antineopteres) are emitted from the nucleus. The common beta decay process involves neutrons in the nucleus, which are converted into protons by electrons and antineutrino emissions.

If neutrinos have their own antiparticles, the electron antineutrinos emitted can be absorbed by other neutrons in the nucleus as neutrinos, resulting in a second beta decay and other electron emissions. Although there are no complete neutrino emissions, the nucleus has undergone double beta decay and remains behind with two additional protons.

Explanation of neutrino mass
Neutral, which is an antiparticle of their own, can help explain why neutrinos have a massive effect that is not explained by the standard model of particle physics.

We must find a mechanism to generate neutrino mass, explained theoretical physicist Werner Rodehoan from the Max Planck Institute for Nuclear Physics at Heidelberg. Rodejohann continued: “In the standard neutron mass model, you have the same amount of matter and antimatter as those produced in the early universe, so they will only destroy the universe with radiation, but because we are here, we know that something is a bit asymmetry between matter and antimatter must be permitted.

Neutral double-beta decay will confirm many of our ideas for survival. “However, observing this is very difficult: The enriched xenon observatory (EXO) in New Mexico is looking for dual neutral beta decay in 200 kg of xenon-136-enriched xenon xenon, a neutron-rich nucleus, as an important candidate considered for the procedure.

The idea is that two high-energy electrons emitted during the decay process ionize other xenon atoms, creating an electronic shower that can be detected.
