Abstract

We consider O(αs) corrections to the squared masses of the pseudo-Goldstone excitations about the ground state of dense quark matter. We show that these contributions tend to destabilize the vacuum, leading to a surprisingly complex phase structure for quark matter as a function of quark mass, even for small αs. In particular we find two new phases of CFL quark matter possibly relevant for the real world, for which θ¯QCD=π/2.
