Proposed around 80 years ago by the theoretical physicist Enrico Majorana, these hypothetical elementary particles are their own antiparticle
It will monitor an even higher number of atoms to prove neutrinos indeed act as their own antiparticle
A blip of electric current at the end of an atom-thick wire has brought physicists one step closer to confirming the existence of Majorana particles, entities that are their own antiparticles
If we neglect the decay contributions and consider only the primordial yield, the antiparticle
to particle ratios are found to be controlled only by their respective fugacities.
That is, for each outcoming particle, in Feynman diagrams, there is incoming antiparticle
with positive energy and negative mass, depending on the coupling constant behavior (this is at high energy for the electromagnetic interaction and at low energy for the strong interaction, quarks and gluons).
TEHRAN (FNA)- Most of the laws of nature treat particles and antiparticles
equally, but stars and planets are made of particles, or matter, and not antiparticles
, or antimatter.
But Majorana fermions, first theorized over 70 years ago, are a class of particles that are their own antiparticle
. They might have potential applications for storing data in future quantum computers.
Up to this point, the leptons that were known included the electron, the electron neutrino, and their antiparticles
and the muon, the muon neutrino, and their antiparticles
to particle production ratios in hadron-hadron and d-Au collisions in the DPMJET-III Monte Carlo model," Physical Review C, vol.
Both feature 2D Dirac fermions (fermions that aren't their own antiparticle
), which give rise to extraordinary and highly coveted physical properties.
First proposed more than 70 years ago, a Majorana fermion is a theoretical type of particle that is its own antiparticle
. Electrons and quarks and other particles of matter all have oppositely charged antimatter partners.
* Spacetime symmetry PT amounts to exchanging emission of a particle and absorbtion or an antiparticle
(or vice versa), an operation labeled C.
