Hadrons are elusive superstars of the subatomic world, making up almost all visible matter, and British theoretical physicist Antoni Woss has worked diligently with colleagues at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility to get to know them better. Now, Woss’ doctoral thesis on spinning hadrons has earned him the 2019 Jefferson Science Associates Thesis Prize.
Precise Measurement of Pions Confirms Understanding of Fundamental Symmetry
Nuclear physicists have announced the most precise measurement yet of the ultra-short lifetime of the neutral pion. The result is an important validation of our understanding of the theory of quantum chromodynamics, which describes the makeup of ordinary matter. The research, carried out at the Department of Energy’s Thomas Jefferson National Accelerator Facility, was recently published in the journal Science.
