LEXINGTON, Ky. (April 2, 2019) — A team of researchers from the University of Kentucky College of Arts and Sciences Department of Physics and Astronomy has made a discovery that has changed the "elementary textbook" description of protons.
Professors Keh-Fei Liu and Terrence Draper, along with postdoctoral scholar Jian Liang, are co-authors of a study titled "Proton Mass Decomposition from the QCD Energy Momentum Tensor" that was published this past fall in Physical Review Letters. Since then, the study has gained national attention in the world of physics, as its results have opened doors for more calculations and theoretical understanding.
