like bound Majorana fermions. However, instead of a single fundamental particle, they are the collective movement of several individual particles (themselves...

of particles known as fermions, there should be particles that are their own antiparticles. Solution of the Majorana equation yields those particles, now...

fermions that are their own antiparticle. Particles corresponding to this equation are termed Majorana particles, although that term now has a more expansive...

This is a list of known and hypothesized particles. Elementary particles are particles with no measurable internal structure; that is, it is unknown whether...

obey the Pauli exclusion principle. These particles include all quarks and leptons and all composite particles made of an odd number of these, such as all...

be another type of spin ⁠ 1 /2⁠ particle called Majorana particles, named after the Italian physicist Ettore Majorana who first proposed the concept....

antiparticle, now known as a Majorana particle. In 1939, Wendell H. Furry proposed that if neutrinos are Majorana particles, then double beta decay can proceed...

particle, which is not composed of other particles (for example, quarks; or electrons, muons, and tau particles, which are called leptons). Particle physics...

problem in physics. Particle physicists study matter made from fundamental particles whose interactions are mediated by exchange particles – gauge bosons –...

In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model...

grains: particle models work across a huge scale. Unlike waves, particles do not exhibit interference. Classical waves interfere. Particles follow trajectories...

gravitons. For a spin-½ particle such as the neutralino, being truly neutral implies being a Majorana fermion. Composite particles can also be truly neutral...

fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are...

the Majorana spinor. There also does not seem to be any particular prohibition to having Weyl spinors appear in nature as fundamental particles. The...

distinguish in an absolute sense particles of matter and particles of antimatter. This is particularly easy for those particles that carry electric charge,...

theoretical radioactive decay process that would prove a Majorana nature of the neutrino particle. To this day, it has not been found. The discovery of neutrinoless...

between other particles, while one (the Higgs boson) contributes to the phenomenon of mass. Other bosons, such as mesons, are composite particles made up of...

quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other...

A strange particle is an elementary particle with a strangeness quantum number different from zero. Strange particles are members of a large family of...

at least two undetected particles for which we have no conventional explanation." The need for at least two undetected particles was shown by the inability...
