New Method Could Explore Gluon Saturation at the Future Electron-Ion Collider
Exploring the gluon saturation in large nuclei is one of the major goals of the future Electron-Ion Collider. New research proposes a novel method to probe the onset of gluon saturation by measuring the nucleon energy-energy correlation in deep inelastic scattering. This result leads to a comprehensive approach to study the universal behavior of gluon saturation.
SLAC theorist Lance Dixon receives Galileo Galilei Medal
Lance Dixon, professor of particle physics and astrophysics at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, will receive the 2023 Galileo Galilei Medal for his contributions to theoretical physics. The award was announced by the Italian National Institute of Nuclear Physics (INFN) on Feb. 15 – the 459th birthday of Galileo.
Data Reveal a Surprising Preference in Particle Spin Alignment
Given the choice of three different “spin” orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher at Brookhaven National Laboratory, appear to have a preference. Recent results reveal a preference in global spin alignment of particles called phi mesons.
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.
