The Delta baryons are combinations of up and down quarks. They’re like the proton and the neutron, 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.

Antimatter is uncommon, but it’s not exactly rare. Antiparticles - especially those generated by cosmic radiation - are all around us, all the time. But just what is it doing here? As we discuss, the role of antimatter is fundamentally tied to our experience of reality.

Novel technology and perhaps physics awaits us if we’re brave enough to build one.
Particle Physics is a source of more than just fascinating questions. Today we give four important reasons why we should build another particle collider. Share these four reasons with someone, especially if they aren't bought in!
