Neutrinoexperimente

NeutrinoExperimente is a neutral term used to describe experimental programs devoted to studying neutrinos, the nearly massless, electrically neutral leptons that interact primarily via the weak nuclear force. The field encompasses research on neutrino production, propagation, interactions, and their implications for particle physics and cosmology. Objectives include determining neutrino masses and mixing, testing the Standard Model, and exploring phenomena such as sterile neutrinos and charge-parity (CP) violation in the lepton sector.

Experiments use diverse detection methods and sources. Detectors often rely on large volumes of water, liquid scintillator, or liquid argon to observe faint signals from neutrino interactions. Common sources include nuclear reactors, the Sun, cosmic-ray interactions in the atmosphere, and particle accelerators. Notable techniques include Cherenkov light detection, scintillation light, and time projection chamber readouts.

Historically, neutrino experiments led to the discovery of neutrino flavor oscillations, establishing that neutrinos have mass. Landmark programs include Super-Kamiokande, SNO, KamLAND, and reactor-based experiments such as Daya Bay and RENO, which measured mixing angles and mass-squared differences. Ongoing projects probe CP violation, the neutrino mass ordering, and searches for sterile species, while historic and modern detectors also contribute to high-energy neutrino astronomy, including observations of atmospheric and astrophysical neutrinos.

Looking ahead, NeutrinoExperimente continues with major facilities such as Hyper-Kamiokande, the Deep Underground Neutrino Experiment (DUNE), JUNO, and KM3NeT. These efforts seek to resolve the remaining unknowns about the neutrino sector and to enable precision tests of fundamental physics and early-universe processes. Related topics include neutrino oscillations, neutrino mass, astrophysical neutrinos, and lepton CP violation.
