Title
Color Superconductivity: Symmetries and Effective Theories
Abstract
I review the low energy theory for 2 flavor QCD relevant for high matter density. For the 3 flavor case I will show how to construct the topological Wess-Zumino action needed to describe the time honored process: neutral pion decay into two photons. I will then show how the electroweak processes are modified at finite density. Links to the 't Hooft global anomaly conditions are also considered. Finally I will suggest a new way to link color superconductivity to the physics of Compact stars (like Supernova-relics).
