UC physicists outline next 10 years of neutrino research
3 天之前 · But unexpected experimental results made physicists suspect there might be another neutrino flavor, called a sterile neutrino because it appears immune to three of the four known “forces.” “Theoretically, it interacts with gravity, but it has no interaction with the others, weak nuclear force, strong nuclear force or electromagnetic force ...

2024年11月28日 · KM3NeT/ORCA is an underwater neutrino telescope under construction in the Mediterranean Sea. Its primary scientific goal is to measure the atmospheric neutrino oscillation parameters and to determine the neutrino mass ordering. ORCA can constrain the oscillation parameters $Δm^{2}_{31}$ and $θ_{23}$ by reconstructing the arrival direction and energy of …

2024年11月16日 · neutrino, elementary subatomic particle with no electric charge, very little mass, and 1 / 2 unit of spin. Neutrinos belong to the family of particles called leptons, which are not subject to the strong force. Rather, neutrinos are subject to the weak force that underlies certain processes of radioactive decay.

2024年11月28日 · Is the Great Neutrino Puzzle Pointing to Multiple Missing Particles? Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
