No one really knows what happens inside an atom. But two competing groups of scientists think they've figured it out. And both are racing to prove that their own vision is correct. Still, no one knows ...

Just as people behave differently as couples than as individuals, protons and neutrons (also known as nucleons) inside the nucleus of the atom behave differently in pairs. Just as people behave ...

In this video, we explore fundamental concepts about the atom and the forces that govern it. **CHAPTERS** 0:00 - Why is the Universe inside an atom? 1:29 - What is an atom? 4:44 - Louis de Broglie's ...

Though atomic nuclei are often depicted as static clusters of protons and neutrons (nucleons), the particles are actually bustling with movement. Thus, the nucleons carry a range of momenta. Sometimes ...

In 2013, scientists announced the discovery of Zc(3900): the first confirmed particle made of four quarks. Ultimately, quarks – other than being part of our namesake – are the infinitesimally small ...

Researchers perform a global analysis of lead-lead collisions, finding that agreement with the reaction rate requires a much smaller nucleus. Low-energy experiments find a nucleon size of around 0.5 ...

A careful re-analysis of data taken as revealed a possible link between correlated protons and neutrons in the nucleus and a 35-year-old mystery. The data have led to the extraction of a universal ...

Nuclear forces can be compared to a game of catch. With the two-nucleon force, two players, or nucleons, interact by throwing a ball to each other. The ball, a subatomic particle called a meson, can ...

The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this phenomenon that could have broad implications for ...
