Majorana neutrino

Target entity: Majorana neutrino
Context triple: [Ettore Majorana, hasConceptNamedAfter, Majorana neutrino]

• A. Neutrino
  A neutrino is an extremely light, electrically neutral elementary particle that interacts only via the weak nuclear force and gravity, making it very difficult to detect.
• B. neutrino hypothesis
  The neutrino hypothesis is Wolfgang Pauli’s 1930 proposal of a neutral, nearly massless particle to explain missing energy and momentum in beta decay, laying the groundwork for the discovery of the neutrino.
• C. neutrino oscillation
  Neutrino oscillation is a quantum phenomenon in which neutrinos change from one flavor type to another as they travel, implying that they have mass and mix between flavor states.
• D. Fermion
  A fermion is a fundamental particle or composite particle that follows Fermi–Dirac statistics and the Pauli exclusion principle, forming the basic building blocks of matter such as electrons, protons, and neutrons.
• E. Kobayashi–Maskawa theory
  The Kobayashi–Maskawa theory is a fundamental framework in particle physics that explains CP violation in the Standard Model through a three-generation quark mixing matrix (the CKM matrix).
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Majorana neutrino
Target entity description: A Majorana neutrino is a hypothetical type of neutrino that is its own antiparticle, with important implications for particle physics and the matter–antimatter asymmetry in the universe.
