D-terms in Bosonic and Fermionic Systems

The most fundamental information about a particle is contained in the matrix elements of its energy-momentum tensor (EMT): the mass and spin. But the EMT contains more information than that. Equally important yet far less known is the D-term and with it, the information contained in the spatial components of the EMT. The D-term and the spatial components of the EMT show in detail how the strong forces inside the nucleon balance to form a bound state and provides unique insights on the nucleon structure. The goal of this thesis is to contribute to a better understanding of the physics associated with the D-term. We investigate the EMT form factors of spin-0 and spin 1/2-particles, focusing especially on the unknown particle property D term.
