Scientists from the University of Kansas developed a technique to track ultra-peripheral collisions between protons and ions, resulting in the creation of gold momentarily. The discovery was made possible by studying photon-photon collisions, which are incredibly clean events with almost nothing else produced.
Robert McKeown, a distinguished service award recipient, has made significant contributions to nuclear physics over the past 50 years. He supervised 14 Ph.D. students and educated thousands of people worldwide through teaching and lecturing at prestigious institutions.
Researchers have developed a new method to image nuclear shapes using high-energy particle smashups at RHIC, revealing subtle details about atomic nuclei. This technique complements lower energy methods and has implications for fields like nuclear fission, neutron stars, and exotic particle decay.
A recent study combines experimental data with state-of-the-art calculations to reveal new details on the origins of proton spin. The research shows that gluons, which hold protons together, contribute significantly to the proton's spin, contradicting earlier findings.
Peter Hurck, the 2023 JSA Postdoctoral Prize winner, is conducting data analyses to identify strange particles and learn about their properties. He hopes to improve data analysis methods for these particles using high-quality data from GlueX experiments.
Researchers have made the first-ever observations of how lambda particles, a form of strange matter, are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). The study reveals that diquarks, pairs of quarks and gluons, can march through atomic nuclei, contributing to the formation of lambdas.
