Scientists gain new insight into how mass is distributed within hadrons

Two-dimensional spatial distribution of mass due to gluons of nucleons (left) and pions (right). It is simulated with a seven-valent pion mass using lattice quantum chromodynamics. Credit: Bigen One Scientists can determine the mass of elementary particles made of quarks by examining the particle’s energy and momentum in four-dimensional spacetime. One of the quantities that encode this information is called…
