In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into it. A recent experiment using the U.S. Department of Energy’s Jefferson Lab ...

Transverse spin asymmetries in high-energy particle collisions are a significant area of research in particle physics, particularly in understanding the internal structure of protons and the dynamics ...

Graphic showing the transverse motion of a quark (green sphere) inside a proton whose spin is aligned to its direction of motion (large yellow arrow). Nuclear theorists at Brookhaven National ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A decade-long mystery has been solved using data from ESA’s X-ray observatory XMM-Newton. The brightest member of the so-called ‘magnificent seven’ has been found to pulsate with a period of seven ...
