The Strength of the Strong Force

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.

Researchers Overcome the Space between Protons and Neutrons to Study the Heart of Matter

Scientists can now study the strong force with a novel method of accessing the space between protons and neutrons within a nucleus. The first direct probes have tested the validity of leading theories that describe the interactions between protons and neutrons in nuclei. This research confirms that current theoretical models describe the behavior of protons and neutrons quite well.

CERN Senior Fellow Dorota Grabowska Receives Leona Woods Lectureship Award

Dorota Grabowska, a senior fellow in the department of theoretical physics at CERN, Europe’s particle physics laboratory, has been named a recipient of the Leona Woods Distinguished Postdoctoral Lectureship Award. The award was established by the physics department at the U.S. Department of Energy’s Brookhaven National Laboratory in honor of renowned physicist Leona Woods to celebrate the scientific accomplishments of outstanding female physicists and physicists from other under-represented minority groups, including the LGBTQ community–and to promote diversity and inclusion in the department.
