The global minimum, with a χ 2 probability of 96%, corresponds to sin 2 (2θ) = 0.23, δm 2 = 8.1 × 10 −4 eV 2, overall neutrino normalization = 1.012, and energy scale = 1.006. The no-oscillation hypothesis is also has a high χ 2 probability of 93%, corresponding to an overall neutrino normalization = 1.008 and energy scale = 1.011.
Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
Many experiments have taken place that study the same oscillations as in atmospheric neutrino oscillation using neutrinos with a few GeV of energy and several-hundred-km baselines. The MINOS , K2K , and Super-K experiments have all independently observed muon neutrino disappearance over such long baselines.
MiniBooNE is a Cherenkov detector experiment at Fermilab designed to observe neutrino oscillations (BooNE is an acronym for the Booster Neutrino Experiment). A neutrino beam consisting primarily of muon neutrinos is directed at a detector filled with 800 tons of mineral oil (ultrarefined methylene compounds) and lined with 1,280 photomultiplier ...
T2K ("Tokai to Kamioka") is a particle physics experiment studying the oscillations of the accelerator neutrinos.The experiment is conducted in Japan by the international cooperation of about 500 physicists and engineers with over 60 research institutions from several countries from Europe, Asia and North America [1] and it is a recognized CERN experiment (RE13).
Main Injector Experiment for ν-A, or MINERνA, is a neutrino scattering experiment which uses the NuMI beamline at Fermilab.MINERνA seeks to measure low energy neutrino interactions both in support of neutrino oscillation experiments and also to study the strong dynamics of the nucleon and nucleus that affect these interactions.
Since neutrino oscillations depend upon the squared mass difference of the neutrinos, neutrino oscillations experience different dynamics than they did in vacuum. Similar to the vacuum case, the mixing angle θ m {\displaystyle \theta _{m}} describes the change of flavors of the eigenstates.
The K2K experiment (KEK to Kamioka) was a neutrino experiment that ran from June 1999 to November 2004. It used muon neutrinos from a well-controlled and well-understood beam to verify the oscillations previously observed by Super-Kamiokande using atmospheric neutrinos .
