Description
Diquarks, correlated quark-quark pairs carrying net color charge, play a key role in both baryon structure and dense quark matter. In this talk I will present results for the vacuum properties of the scalar diquark in a self-consistent and first-principles approach to QCD. Using the functional renormalization group, in particular dynamical hadronization, I will show how the high energy quark and gluon degrees of freedom can be smoothly integrated resulting in a low-energy description in terms of pions, sigma-meson and diquarks. I will show, through direct analytic continuation of the flow equations, that our approach predicts a scalar diquark bound state, supporting the quark-diquark picture of the nucleon.
