Researchers in the College of Arts and Sciences have determined that the lifetime of the so-called charmed omega—part of a family of subatomic particles called baryons—is nearly four times longer than previously thought.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted ...

What was matter like moments after the Big Bang? Particles emerging from the lowest energy collisions of small particles with large heavy nuclei at the Relativistic Heavy Ion Collider (RHIC) could hold the answer. Scientists ...

Quark-gluon plasma is formed as a result of high-energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds (10-24 seconds), this most perfect of all known fluids undergoes rapid hydrodynamic expansion ...

What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case ...
