Abstract

The phase space density, ρ^Q, of quarks in nuclei is studied using realistic models of unintegrated quark distributions, known as transverse momentum densities (TMDs). If this density exceeds unity for matter at normal nuclear densities, the effects of the quark Pauli principle must play a role in nuclei, and models in which the nucleon density at low momentum is small (Quarkyonic matter) may become a starting point for an entirely new description of nuclei. We denote the nuclear density for which ρ^Q=1 to be a transmutation density, n_T, because quark degrees of freedom must be relevant at that density. Including the TMDs of [G. de Teramond et. al, \hrefDOI:https://doi.org/10.1103/PhysRevLett.120.182001 Phys. Rev. Lett. \bf 120, 182002, (2018)] for the valence quarks and phenomenological TMDs for the sea quarks we find that n_T=0.17 ± 0.04 \rm fm^-3, the density of normal nuclear matter. Some of fhe implications of this finding are discussed.
