Unveiling the Mysteries of Proton Structure and Gluon Mass

An experiment conducted at the Thomas Jefferson National Accelerator Facility has revealed the radius of the proton's mass generated by the strong force as it glues together the proton's building block quarks. The result shows that the proton's mass comes from several sources, including the strong force energy that glues quarks together, with this force manifesting as "gluons." The experimenters were able to determine the gluonic mass radius dominated by graviton-like gluons, as well as a larger radius of attractive scalar gluons that extend beyond the moving quarks and confine them.
