Researchers have experimentally extracted the strength of the strong force, a quantity that firmly supports theories explaining how most of the mass or ordinary matter in the universe is generated. This quantity, known as the coupling of the strong force, describes how strongly two bodies interact or “couple” under this force. With Jefferson Lab data, the physicists were able to determine the strong force coupling at the largest distances yet.
The 2022 JSA Postdoctoral Prize winner, Arkaitz Rodas, characterizes lesser-known particles to help physicists understand what holds matter together. Rodas will characterize light mesons using computational mathematical tools for his prize-winning project.
The U.S. Department of Energy (DOE) named three National Laboratory scientists as DOE Office of Science Distinguished Scientists Fellows
Nobuo Sato is working to put the know in femto. He’s just been awarded a five-year, multimillion dollar research grant by the Department of Energy to develop a “FemtoAnalyzer” that will help nuclear physicists image the three-dimensional internal structure of protons and neutrons. Now, Sato is among 76 scientists nationwide who have been awarded a grant through the DOE Office of Science’s Early Career Research Program to pursue their research.
Quarks and gluons are elementary particles that make up everything you see before you, including yourself, and Nobuo Sato wants to know how. At the Department of Energy’s Thomas Jefferson National Accelerator Facility, he will be tackling this question as the recipient of the JSA/Jefferson Lab Nathan Isgur Fellowship for Nuclear Theory.
Low-momentum (wimpy) quarks and gluons contribute to proton spin, offering insights into protons’ behavior in all visible matter. The Science The “proton spin puzzle” concerns how much the building blocks of the proton, quarks and gluons, and their motion within…
