Energy-momentum tensor form factors of the nucleon in nuclear matter

TL;DR

This paper investigates the energy-momentum tensor form factors of the nucleon within nuclear matter using a modified Skyrme model, revealing that medium effects increase the negativity of the D-term, consistent with other methods.

Contribution

It introduces a study of nucleon energy-momentum tensor form factors in nuclear matter using an in-medium modified Skyrme model, highlighting the impact of medium effects on the D-term.

Findings

The D-term is negative, aligning with other approaches.

Medium effects make the D-term more negative.

The study confirms the robustness of the negative D-term in nuclear matter.

Abstract

The nucleon form factors of the energy-momentum tensor are studied in nuclear medium in the framework of the in-medium modified Skyrme model. We obtain a negative D-term, in agreement with results from other approaches, and find that medium effects make the value of d_1 more negative.
