Continuity of quark and hadron matter

We review, clarify, and extend the notion of color-flavor locking. We prese nt evidence that for three degenerate flavors the qualitative features of t he color-flavor locked state, reliably predicted fur high density, match th e expected features of hadronic matter at low density. This provides, in pa rticular, a controlled, weak-coupling realization of confinement and chiral symmetry breaking in this (slight) idealization of QCD.
