Abstract in English

We study multipole expansion of the momentum currents in hadrons with three series and in connection with the gravitational fields generated nearby. The momentum currents are related to their energy-momentum form factors, which in principle can be probed through processes like the deeply virtual Compton scattering currently studied at the Jefferson Lab 12 GeV facility and future Electron-Ion Collider. We define the leading momentum-current multipoles [the "tensor monopole" (T0) and "scalar quadrupole" (S2) moments], relating the former to the so-called D term in the literature. We calculate the momentum-current distribution in the hydrogen atom and its monopole moment in the basic unit of , showing that the sign of the D term has little to do with mechanical stability. The momentum-current distribution also strongly modifies the static gravitational field inside hadrons.

The momentum currents are related to their energy-momentum form factors, which in principle can be probed through processes like the deeply virtual Compton scattering currently studied at the Jefferson Lab 12 GeV facility and future Electron-Ion Collider. We define the leading momentum-current multipoles [the "tensor monopole" $\tau$ (T0) and "scalar quadrupole" $\hat{\sigma} ^{ij}$ (S2) moments], relating the former to the so-called D term in the literature. We calculate the momentum-current distribution in the hydrogen atom and its monopole moment in the basic unit of $\tau_{0} = \hslash^{2} / 4m_{e}$, showing that the sign of the D term has little to do with mechanical stability. The momentum-current distribution also strongly modifies the static gravitational field inside hadrons.pl
