Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

Experimenting in the world of particle physics probably brings to mind large, expensive pieces of equipment like particle accelerators, or at least exotic elements or isotopes that most of us can’t ...
