Abstract
In this talk, we report a recent investigation on the energy-momentum tensor form factors of the nucleon in nuclear medium, based on the framework of the in-medium modified chiral soliton model. The model was constructed by taking into account the influence of the surrounding environment to the mesonic sector (π-, ρ- and ω-meson properties). We briefly discuss the results of the energy-momentum tensor form factors.
Highlights
It is of great importance to study the energy-momentum tensor form factors (EMTFFs), since they shed light on the structure of the nucleon from a new direction
The generalized parton distributions (GPDs) makes it possible to investigate the EMTFFs from hard exclusive reactions,[1,2,3,4] since the Melin transforms of certain GPDs are connected to the EMTFFs that explain how the mass and the spin are distributed inside a nucleon
The nucleon matrix element of the totally symmetric energy-momentum tensor (EMT) operator can be parameterized in terms of three real form factors defined as follows:[5, 6]
