Pressure inside hadrons: criticism, conjectures, and all that

TL;DR

This paper critically examines the interpretation of the energy-momentum tensor form factor $D(t)$ in hadrons, addressing concerns and proposing ways to reconcile these issues with the pressure and shear force distribution interpretation.

Contribution

It reviews existing concerns about the $D(t)$ form factor interpretation and suggests methods to reconcile these concerns with the physical interpretation.

Findings

Identifies key concerns in the interpretation of $D(t)$

Proposes approaches to reconcile theoretical concerns

Clarifies the physical meaning of pressure and shear distributions

Abstract

The interpretation of the energy-momentum tensor form factor $D(t)$ of hadrons in terms of pressure and shear force distributions is discussed, concerns raised in the literature are reviewed, and ways to reconcile the concerns with the interpretation are indicated.
