Majorana fermion
Also known as: Majorana particle
- 1A Majorana fermion is defined as a particle that is its own antiparticle.
- 2The concept was hypothesized by Ettore Majorana in 1937.
- 3It is distinguished from the Dirac fermion model.
- 4The term is a fundamental classification in particle physics.
In particle physics a Majorana fermion or Majorana particle is a fermion that is its own antiparticle.

Pontecorvo was deeply influenced by Ettore Majorana's work and explored the implications of Majorana neutrinos, which are their own antiparticles.
A Majorana fermion, often referred to as a Majorana particle, is a specific type of fermion that acts as its own antiparticle. This concept stands in contrast to the more common Dirac fermion, which describes particles that are distinct from their corresponding antiparticles.

While the Standard Model of particle physics typically categorizes fermions as Dirac particles, the possibility of Majorana fermions remains a significant area of study, particularly in the context of theoretical physics and condensed matter research.
