The sigma meson exists only for a fleeting moment before decaying into a pair of pions, making it hard to study. Nuclear physicists recently combined modern supercomputer calculations with more traditional theoretical tools to study the sigma meson, producing the first accurate theoretical view of the sigma as a system of quarks and gluons. This will aid in understanding the role the sigma meson plays in proton-neutron interactions and other phenomena.A Subatomic Challenge Resolved: Supercomputer Calculations Produce the First Accurate Theoretical View of the Sigma Meson
