Sum Rules in the CFL Phase of QCD at finite density

We study the asymmetry between the vector current and axial-vector current correlators in the colour-flavour locking (CFL) phase of QCD at finite density. Using Weinberg's sum rules, we compute the decay constant $f_\pi$ of the Goldstone modes and find agreement with previous derivations. Using...
