NEW YORK (AP) — A neutrino detector submerged in the Mediterranean Sea has sniffed out the most energetic ghost particle yet, scientists reported Wednesday.. The newly detected neutrino is ...
ICARUS measured speed for seven neutrinos in the same short-pulse beam OPERA had checked in November 2011, and found them, on average, traveling at the speed of light. The results were from a trial run of neutrino-velocity measurements slated for May. [23] In May 2012, a new bunched beam rerun was initiated by CERN.
The water-based detectors Kamiokande II and IMB detected 11 and 8 antineutrinos (lepton number = −1) of thermal origin, [103] respectively, while the scintillator-based Baksan detector found 5 neutrinos (lepton number = +1) of either thermal or electron-capture origin, in a burst less than 13 seconds long. The neutrino signal from the ...
High-energy neutrinos may cause a large signal in the detector, pointing back to their origin. Clusters of such neutrino directions indicate point sources of neutrinos. Each of the above steps requires a certain minimum energy, and thus IceCube is sensitive mostly to high-energy neutrinos, in the range of 10 7 to about 10 21 eV. [15]
In 2018, they found 5σ significance for the existence of neutrinos from the fusing of two protons with an electron (pep neutrinos). [32] In 2020, they found for the first time evidence of CNO neutrinos in the Sun. Improvements on the CNO measurement will be especially helpful in determining the Sun's metallicity.

FASER (ForwArd Search ExpeRiment) is one of the nine particle physics experiments in 2022 at the Large Hadron Collider at CERN.It is designed to both search for new light and weakly coupled elementary particles, and to detect and study the interactions of high-energy collider neutrinos. [1]
This new detector will feature a drastically larger amount of water as its predecessor, Super-Kamiokande, with 266 kilotons of water in its tank. With hopes to measure neutrino interactions and the DSNB with much more precision and lower background noise, the HK detector is set to begin collecting data some time in 2027.
