Physicists know from previous experiments that what happens at the nuclear scale to protons and neutrons also affects their ...

Experimental particle physicist Ian Shipsey, a remarkable leader and individual, passed away suddenly and unexpectedly in ...

The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this expansion was powered by a new entity in the universe, known as the ...

Scientists at the Relativistic Heavy Ion Collider (RHIC) have found new evidence that collisions of small nuclei with large ones can create tiny specks of quark-gluon plasma (QGP), a state of ...

In the Big Bang, matter and antimatter should have been created in equal amounts. But fast forward 13.8 billion years to the present day, and the universe is made almost entirely of matter, so ...

Jets are created when a quark or gluon within a proton or neutron in one of RHIC's ion beams collides intensely with a quark or gluon in the nuclear particles that make up the beam traveling in ...
