Adding an exotic particle known as a Xi hyperon to a helium nucleus with three nucleons could produce a nucleus that is temporarily stable, calculations by RIKEN nuclear physicists have predicted.

Strange matter only occurs under very specific circumstances -- and astrophysicists are getting closer to understanding what ...

Newport News, Va. -- In research performed at the Department of Energy's Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result ...

Some neutron stars probably have something strange lurking in their cores, according to a recent study. Neutron stars are already some of the most peculiar objects in the universe. They contain enough ...

CHAMPAIGN, Ill. — An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. Quarks are subatomic ...

In particle physics, the term "strange matter" or "strange quark matter" refers to a hypothetical, soup-like existence, made of a trio of quarks. But what's so "strange" with this matter? According to ...

The lightest neutron star ever found, at around 0.77 times the mass of the sun, no longer fits with our understanding of how these stars form. It might even contain exotic matter like strange quarks.

Matter is built around quarks, forming the nuclei of the atoms and molecules. While there are six types of quarks, regular matter contains only two: up quarks and down quarks. Protons contain two ups ...
