Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes ...

One of them, his concept of 'Majorana fermions' — particles that are their own antiparticle — is finding ever wider relevance in modern physics. Enrico Fermi had to cajole his friend Ettore ...

There's a reason they're known as ghost particles. Antineutrinos are the antiparticle counterpart to neutrinos. Usually, an antiparticle has the opposite charge to its particle equivalent ...

As of 2024, all fermions except for the neutrino have been proven to have a distinct antiparticle, implying that they are not Majorana fermions and are termed Dirac fermions. While they are a ...
