Electroweak Physics for Color Superconductivity
We construct the effective theories describing the electroweak interactions
for the low energy excitations associated with the color superconductive phases
of QCD at high matter density. The main result, for the 3 flavor case, is that
the quasiparticle Goldstone boson decay into two physical massless
photons is identical to the zero density case once we use the new Goldstone
decay constant and the modified electric charge ,
with and the strong coupling constant. For 2
flavors we find that the coupling of the quarks to the neutral vector boson
is modified with respect to the zero density case. We finally point out
possible applications of our result to the physics of compact objects.Comment: 23 pages, 1 Figure, RevTex. More discussion and references adde
