In a unique analysis of experimental data, nuclear physicists have made the first-ever observations of how lambda particles, so-called “strange matter,” are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). What’s more, these data hint that the building blocks of protons, quarks and gluons, are capable of marching through the atomic nucleus in pairs called diquarks, at least part of the time. These results come from an experiment conducted at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility.
