Results from the NEOS experiment on sterile neutrinos differ partly from the theoretical expectations

Dubbed as `ghost particles,` neutrinos have no electric charge and their masses are so tiny that they are difficult to observe. The sun, nuclear reactors, supernovae explosions create them, when their nuclei are going through a radioactive decay, known as beta decay. The Center for Underground Physics, within the Institute for Basic Science (IBS) led the Neutrino Experiment for Oscillation at Short Baseline (NEOS) to study the most elusive neutrinos, the so-called `sterile neutrinos`. Their results are now available in the journal Physical Review Letters.
