Strange color superconductivity in QCD

We propose a new state, strange color superconductivity, that appears in strange quark matter when total barion number density is fixed. In this state, heavy squarks, with a small Fermi surface, ’strangly’ pair with light u or d quarks that have a larger nominal Fermi surface, opening a gap there. There are gapless states in the intermediate region. Strange color superconductivity might be realized in quark matter at intermediate densities in neutron stars. We expect a second order phase transition, as a function of increasing density, from this phase to color-flavor locked (CFL) quark matter.
