We report on the first determination of the shear forces quarks inside the proton from experimental data on deeply virtual Compton scattering. The maximum shear force of approximately 40 MeV/fm occurs near 0.6 fm from the proton center, indicating where confinement forces may be strongest. On the macroscopic scale of the earth surface, this force corresponds to the weight of a mass of about 650 kg. The shear forces in the proton reverse direction at r = 0.45 fm from the center.

    Charmonium-nucleon femtoscopy is proposed as a probe of the nucleon D-form factor by constructing an effective potential from lattice gravitational form factors and matching it to HAL QCD results.
