Description
Understanding the QCD phase diagram is a major challenge in high-energy physics.
To this end, two-color QCD offers an ideal theoretical laboratory since, unlike real-world QCD, its dynamics at finite density can be investigated via lattice simulations.
In this talk, I will use chiral perturbation theory to discuss the infrared dynamics of two-color QCD at finite density by focusing on the impact of the θ-angle on the vacuum properties, symmetries, and spectrum.
In particular, I will describe the rich phase diagram of the theory for different numbers of flavors. I will put special emphasis on the diquark condensation phenomenon and the fate of CP symmetry at θ=π.
Finally, I will briefly comment on the significance of the results for QCD at finite quark chemical potential.
