They’re like the <a href="https://pasayten.org/the-field-guide-to-particle-physics/proton">proton</a> and the <a href="https://pasayten.org/the-field-guide-to-particle-physics/neutron">neutron</a>, only much more heavy and much less stable. They all seem to have about the same mass - around 1232 MeV, but we don’t really have a good handle on it. That is mostly because the Delta baryons lives are so short. They decay extremely quickly, in 5.6×10^−24 seconds. There are four delta baryons, corresponding to all triplet combinations of <a href="https://pasayten.org/the-field-guide-to-particle-physics/up-and-down-quarks">up and down quarks</a>:<ul> <li>Δ++ = uuu, made from three up quarks, which has an electric charge of +2e </li> <li>Δ+ = uud, made from two up quarks and one down, which has an electric charge of +e </li> <li>Δ0 = ddu, made from two up quarks and one down, which has an no electric charge </li> <li>Δ- = ddd, made from three down quarks, which has an electric charge of -e </li> </ul>What makes these combinations different from protons and neutrons is their spin. The uud of the Δ+ might look like a proton, but it has a higher intrinsic angular momentum. The quarks are zooming around each other - and all that subnuclear goo - with more energy than they do i
