Scientists in the US have utilized the Polaris supercomputer to generate the most detailed three-dimensional (3D) images of the pion, the lightest particle made of quarks. The study, which helped reveal the internal structure of a pion in unprecedented detail, was conducted by a research team at the US Department of Energy’s (DOE) Argonne National Laboratory (ANL). Pions are subatomic particles that play a significant role in holding atomic nucl…
