The omega baryons are a family of subatomic hadron (a baryon) particles that are represented by the symbol. Ω. and are either neutral or have a +2, +1 or −1 elementary charge.
Δ−. (ddd), which respectively carry an electric charge of +2 e, +1 e, 0 e, and −1 e . The Δ baryons have a mass of about 1 232 MeV/c2; their third component of isospin and they are required to have an intrinsic spin of 3 2 or higher (half-integer units). Ordinary nucleons (symbol N, meaning either a proton or neutron ), by contrast, have ...
