Vor 16 Stunden · The lightweight particles morph from one variety of neutrino to another as they travel, a strange phenomenon called neutrino oscillation (SN: 10/6/15). That ability rests on quantum uncertainty, a ...
Vor 4 Tagen · Sobald die freien Neutronen aufgebraucht sind, werden die in den Kernen gebundenen Neutronen durch weitere Neutrino-Absorptionen in Protonen umgewandelt, wodurch Atomkerne nahe der Beta-Stabilitätslinie und sogar darüber hinaus erzeugt werden. Die Energie der Neutrinos ist groß genug, um Kerne in Zustände anzuregen, die durch die Emission von Neutronen, Protonen und Alphateilchen zerfallen ...
22. Mai 2024 · The answer lies in the fact that stopping a neutrino is a probabilistic phenomenon, just like the lifetime of a human being. The average life span is close to 80 years, but some die in infancy, and a few cross 100. So, in a huge stream of neutrinos, a few, maybe one or two, will be stopped within a short distance.
Vor 5 Tagen · In a study recently submitted to Physical Review Letters, the IceCube Collaboration presents an improved measurement of neutrino oscillation parameters using the largest atmospheric dataset of over 150,000 candidate neutrino events between 5 GeV and 100 GeV and an advanced reconstruction method based on convolutional neural networks ...
Vor 3 Tagen · Ultra-high energy (UHE) neutrino astronomy is aiming for higher energy (>10 15 eV) neutrinos which have travelled cosmologically interesting distances. A single UHE neutrino with an energy of 3x10 20 eV has the same energy as the tennis ball from a Murray 1st serve, but they occur much less frequently.
Vor 5 Tagen · Unlike lower energy atmospheric neutrinos that easily oscillate, a TeV muon neutrino would need to journey over 500,000 kilometers—more than 40 times the Earth’s diameter—before it is expected to oscillate. As such, the atmospheric neutrino flux is expected to remain unaffected at higher energies.
Vor 16 Stunden · The new experiment studied neutrinos produced in the decay of beryllium-7 through electron capture, determining that the neutrinos have a wave packet size of at least 6.2 trillionths of a meter. By implanting beryllium-7 atoms in a sensitive device and studying the energy of the recoil when the atoms transformed, the researchers were able to measure the minimum size of the neutrino wave packet.
