LHC: Five new particles hold clues to sub-atomic glue

The Large Hadron Collider has discovered new sub-atomic particles that could help to explain how the centres of atoms are held together.
The particles are all different forms of the so-called Omega-c baryon, whose existence was confirmed in 1994.
Physicists had always believed the various types existed but had not been able to detect them - until now.
The discovery will shed light on the operation of the "strong force", which glues the insides of atoms.

Proton Dripping Tests a Fundamental Force in Nature

Like gravity, the strong interaction is a fundamental force of nature. It is the essential "glue" that holds atomic nuclei - composed of protons and neutrons - together to form atoms, the building blocks of nearly all the visible matter in the universe. Despite its prevalence in nature, researchers are still searching for the precise laws that govern the strong force. However, the recent discovery of an extremely exotic, short-lived nucleus called fluorine-14 in laboratory experiments may indicate that scientists are gaining a better grasp of these rules.
