Along with quantum mechanics, Einstein’s special theory of relativity serves as the basis of the Standard Model of particle physics. At its heart is a concept called Lorentz ... In this case, a ...
Atomic and molecular physics it the study of the properties, dynamics and interactions of the basic (but not fundamental) building blocks of matter. A crucial component of this is understanding ...
What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper ...
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 ...
Since the start of the 20th century, physicists have discovered a veritable zoo of subatomic particles ... (The protons are confined to the atomic nuclei.) The energy of these electrons is ...
Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' entropy ... when protons are locked inside atomic nuclei. "Because nuclei are made of protons ...
This is possible because just as a RHIC collision can kick an energetic quark or gluon free, that interaction can also produce a high energy photon, or particle of light. These direct photons are ...
