Majorana Spinors

Majorana spinors are a special type of mathematical object used in quantum physics to describe particles called fermions, such as neutrinos, that are their own antiparticles. Unlike most particles, which have distinct antiparticles with opposite properties, Majorana particles are unique in that the same entity acts as both. This concept is important in understanding fundamental symmetries in nature and could have implications for understanding the universe's composition, including the elusive nature of dark matter. In essence, a Majorana spinor provides a framework where a particle and its antiparticle are indistinguishable.
