We study the energy-momentum tensor of spin-0 and spin-12 hadrons in momentum space.We parametrize this object in terms of so-called gravitational transverse-momentum distributions, and we identify 350 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 Hair distribution in momentum space, revealing part of the wealth of physical information that can be gained from higher-twist transverse-momentum distributions.
