Majorana spinor

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

• A. Dirac spinors
  Dirac spinors are four-component mathematical objects in relativistic quantum mechanics that describe spin-½ particles, such as electrons, incorporating both their spin and particle–antiparticle degrees of freedom.
• B. 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.
• C. Dirac field
  The Dirac field is a quantum field describing spin-½ fermions, such as electrons and quarks, incorporating both special relativity and quantum mechanics.
• D. Infeld–van der Waerden formalism
  The Infeld–van der Waerden formalism is a mathematical framework in general relativity that reformulates the theory using spinor calculus to describe gravitational and electromagnetic fields.
• E. Dirac equation
  The Dirac equation is a fundamental relativistic wave equation in quantum mechanics that describes spin-½ particles such as electrons and predicts phenomena like antimatter.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Majorana spinor
Target entity description: A Majorana spinor is a type of spinor in quantum field theory that describes a fermion which is its own antiparticle, satisfying a real-valued condition under charge conjugation.
