What is the difference between neutrons and antineutrons

Some particles, however, have proven especially difficult to create. The ability to produce these elusive particles without dedicated facilities could fast-track research in nuclear and particle physics, such as studies of hyperon-nucleon interactions and the role of hyperons in neutron stars. Current methods generate these particles only in relatively small quantities. Furthermore, some production pathways—such as the proton-antiproton annihilation reactions that produce antineutrons—yield particles whose momentum and direction are difficult to measure, making them inadequate for many research purposes.

These particles are a promising source because they often decay into antineutrons or hyperons and are themselves a relatively common product of electron-positron annihilations. The idea i have is that the Anti Neutron is the fussion of an anti proton and an anti electron a positron, i do not know the anti particle of proton. Hello Killian, thanks for your very interesting question.

When you talk about particles, the charge and the mass are not the only possible descriptive elements we use. If you try to describe a person around you, you would use many items such as weight, hight, color of eyes, color of hair, Similarly, particles are described by many quantities, such as charge, mass, spin, isospin, lepton number, In case of antiparticles, some of the above listed items are the same as for the particle as for instance mass, spin, In the case of a neutron, you are very much right, the charge cannot be opposite, since it does not have a charge.
