Abstract
We study color superconductivity in QCD at an asymptotically large chemical potential. In this limit, pairing is dominated by perturbative one-gluon exchange. We derive the Eliashberg equation for the pairing gap and solve this equation numerically. Taking into account both magnetic and electric gluon exchanges, we find with verifying a recent result by Son. For chemical potentials that are of physical interest, the calculation ceases to be reliable quantitatively, but our results suggest that the gap can be as large as 100 MeV.
