One called ARCA - 3,450 meters (2.1 miles) deep near Sicily - is designed to find high-energy neutrinos. One called ORCA - 2,450 meters (1.5 miles) deep near Provence, France - is designed to ...
Several experiments have been and are being conducted to search for this process, e.g. GERDA, [43] EXO, [44] SNO+, [45] and CUORE. [46] The cosmic neutrino background is also a probe of whether neutrinos are Majorana particles, since there should be a different number of cosmic neutrinos detected in either the Dirac or Majorana case.

Various detection methods have been used. Super Kamiokande is a large volume of water surrounded by phototubes that watch for the Cherenkov radiation emitted when an incoming neutrino creates an electron or muon in the water. The Sudbury Neutrino Observatory was similar, but used heavy water as the detecting medium.
A small (under 1%) but robust anisotropy has been observed in cosmic ray muons. [38] In November 2013 it was announced that IceCube had detected 28 neutrinos that likely originated outside the Solar System and among those a pair of high energy neutrinos in the peta-electron volt range, making them the highest energy neutrinos discovered to date ...
Since neutrinos are very difficult to detect, the only bodies that have been studied in this way are the sun and the supernova SN1987A, which exploded in 1987. Scientist predicted that supernova explosions would produce bursts of neutrinos, and a similar burst was actually detected from Supernova 1987A.
The light-dark matter particles hypothesized with scattering properties similar to the neutrinos, and which interact with the Standard Model particles through ‘portal mediators’, could also be possibly detected as FIPs, [12] although they will have to be separated from the neutrino scattering background.
In order to study neutrino oscillations and various fundamental topics of modern physics, neutrinos of astronomic or solar sources, and CERN Neutrinos to Gran Sasso (CNGS) beam produced 730 km away by the Super Proton Synchrotron from CERN, have been detected. The CNGS neutrinos are also studied by the OPERA experiment, therefore those ...
The neutrinos were calculated to have arrived approximately 60.7 nanoseconds (60.7 billionths of a second) sooner than light would have if traversing the same distance in vacuum. After six months of cross checking, on September 23, 2011, the researchers announced that neutrinos had been observed traveling at faster-than-light speed. [6]
