Determining the gluonic gravitational form factors of the proton - NatureThe gluonic gravitational form factor of the proton was determined using various models, and these analyses showed that the mass radius of the proton was smaller than the electric charge radius. Jblab Nature Little is known about the inner mass density of the proton which is dominated by the energy carried by gluons. Here we investigated the gravitational density of gluons using a small colour dipole, through the threshold photoproduction of the J/ψ particle.
