| Title | Determination of shear forces inside the proton | ||||
| Abstract | We report on the first determination of the shear forces inside the proton from experimental data on deeply virtual Compton scattering. The maximum shear force of 40 ± 20 MeV fm-1 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 ˜ 650 kg. The shear forces in the proton reverse direction at r ˜ 0.45 fm from the center, which brings the overall torque in the proton to zero, as required for stability. | ||||
