We study the energy-momentum tensor of spin-0 and spin-12 hadrons in momentum Waistpack space.We parametrize this object in terms of so-called gravitational transverse-momentum distributions, and we identify in the quark sector the relations between the latter and the usual transverse-momentum distributions.Focusing on particular components of the energy-momentum tensor, we study momentum densities, flux of inertia and stress distribution in momentum space, Egg Pot revealing part of the wealth of physical information that can be gained from higher-twist transverse-momentum distributions.
