Energy-momentum tensor form factors of the nucleon within a $\pi$-$\rho$-$\omega$ soliton model

Abstract

We investigate the energy-momentum tensor form factors of the nucleon within the famework of a chiral soliton model, including the $\rho$ and $\omega$ vector mesons. We examine the role of each meson degrees of freedom in these form factors. It is explicitly shown that the pion provides strong attraction whereas the $\rho$ and $\omega$ yield repulsion in such a way that the soliton becomes stabilized. The results are discussed in comparison with those of other models.
