This measurement was repeated in 2007 using the MINOS detectors, which found the speed of 3 GeV neutrinos to be, at the 99% confidence level, in the range between 0.999 976 c and 1.000 126 c. The central value of 1.000 051 c is higher than the speed of light but, with uncertainty taken into account, is also consistent with a velocity of exactly ...
These restrictions were later improved by the SK team after improvements to the detector and were then found to be ¯ for neutrinos at energies above 17.3 MeV. [7] In 2021, based on SK-IV measurements up to 2018, the limit was strengthened to 2.7 ν e ¯ c m − 2 s − 1 {\displaystyle 2.7{\bar {\nu _{e}}}\,\mathrm {cm} ^{-2}\,\mathrm {s} ^{-1 ...
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 CNGS neutrinos are also studied by the OPERA experiment, therefore those experiments are also called CNGS1 (OPERA) and CNGS2 (ICARUS). [5] The CNGS measurements also became important when the OPERA group announced in September and November 2011 that they had measured superluminal neutrinos (see faster-than-light neutrino anomaly). Shortly ...
No oscillations were found until a detector was installed at a distance 1–2 km. Such oscillations give the value of the parameter θ 13. Neutrinos produced in nuclear reactors have energies similar to solar neutrinos, of around a few MeV. The baselines of these experiments have ranged from tens of meters to over 100 km (parameter θ 12).
Those include blood glucose levels, blood pressure, waist circumference, cholesterol profile (the body's levels of triglycerides, a type of harmful fat found in the blood), and high-density ...
It is believed that, if neutrinoless double beta decay is found under certain conditions (decay rate compatible with predictions based on experimental knowledge about neutrino masses and mixing), this would indeed "likely" point at Majorana neutrinos as the main mediator (and not other sources of new physics).
