Describing matter under extreme conditions, such as those found inside neutron stars, remains an unsolved problem. The density of such matter is equivalent to compressing around 100,000 Eiffel Towers ...

UPTON, NY--Nuclear physicists from around the world seeking to understand the intricate details of the building blocks of visible matter are meeting in Venice, Italy, May 13-19, to discuss the latest ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Quark-gluon plasma (QGP) is a state of matter existing at extremely temperatures and densities, such as those that occur in collisions of hadrons (protons, neutrons and mesons). Under so-called ...

In a never-before-seen particle, four quarks of a feather flock together. Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind. This ...
