Description
This talk will present radiative corrections and their interpretation for the so-called D-term. This is related to the Electron-Ion Collider project, where Generalized Parton Distributions (GPD) will be measured. GPD give access to matrix elements of the energy-momentum tensor of a nucleon. The D-term is sometimes roughly interpreted as characterizing pressure distribution. Calculated it in simple bound states such as the hydrogen atom it exhibits an interesting new type of a log correction that resembles the Lamb shift but has a different physical interpretation.
