High-energy particle collisions reveal the unexpected

The nucleus of an atom is composed of protons and neutrons, which are themselves made up of elementary particles called quarks and gluons. Observing these elementary particles is difficult and typically involves smashing ...

Quarks in six-packs: Exotic Particle Confirmed

For decades, physicists have searched in vain for exotic bound states comprising more than three quarks. Experiments performed at Jülich's accelerator COSY have now shown that, in fact, such complex particles do exist in ...

Physicists confirm existence of new type of meson

(Phys.org) —Physicists in the College of Arts and Sciences at Syracuse University have made several important discoveries regarding the basic structure of mesons—subatomic particles long thought to be composed of one ...

How CERN's discovery of exotic particles may affect astrophysics

You may have heard that CERN announced the discovery of a strange particle known as Z(4430). A paper summarizing the results has been published on the physics arxiv, which is a repository for preprint (not yet peer reviewed) ...

Generations of supercomputers pin down primordial plasma

(Phys.org) —Supercomputers are constantly evolving to meet the increasing complexity of calculations ranging from global climate models to cosmic inflation. The bigger the puzzle, the more scientists and engineers push ...

Titan Project explores the smallest building blocks of matter

(Phys.org) —Our world is made up of particles so tiny they may actually be points in space. These are quarks, relative newcomers to the physics conversation that were not even postulated until the mid-1960s. Put them together ...

First joint result from LHC and Tevatron experiments

(Phys.org) —Scientists working on the world's leading particle collider experiments have joined forces, combined their data and produced the first joint result from Fermilab's Tevatron and CERN's Large Hadron Collider (LHC), ...
