The gravitational form factor D(t) of the electron
Andreas Metz, Barbara Pasquini, Simone Rodini
The electron-graviton interaction can be described in terms of the gravitational form factors of the QED energy momentum tensor. Here we focus on the form factor D(t), and we exami…
Revisiting the proton mass decomposition
Andreas Metz, Barbara Pasquini, Simone Rodini
Different decompositions (sum rules) for the proton mass have been proposed in the literature. All of them are related to the energy-momentum tensor in quantum chromodynamics. We r…
Revisiting model relations between T-odd transverse-momentum dependent parton distributions and generalized parton distributions
B. Pasquini, S. Rodini, A. Bacchetta
We revisit the connection between generalized parton distributions in impact parameter space and T-odd effects in single spin asymmetries of the semi-inclusive deep inelastic proce…
The twist-three distribution in a light-front model
B. Pasquini, S. Rodini
We discuss the twist-three, unpolarized, chiral-odd, transverse momentum dependent parton distribution (TMD) within a light-front model. We review a model-independ…
