We study weak interaction rates involving Goldstone bosons in the neutral kaon condensed phase of color flavor locked quark matter. We identify the dominant processes that contribute to the neutrino mean free path and to neutrino production. We find unique characteristics of weak interaction rates in this novel phase and discuss how they might influence neutrino emission in a core collapse supernova.

Some issues about neutrino processes in color superconducting quark matter
Several relevant issues in computing neutrino emissivity in Urca processes in color superconducting quark matter are addressed. These include: (1) The constraint on u quark abundance is given from
Neutrino scattering off pair-breaking and collective excitations in superfluid neutron matter and in color-flavor-locked quark matter
We calculate the correlation functions needed to describe the linear response of superfluid matter, and go on to calculate the differential cross section for neutral-current neutrino scattering in
Bulk viscosity due to kaons in color-flavor-locked quark matter
We calculate the bulk viscosity of color-superconducting quark matter in the color-flavor-locked (CFL) phase. We assume that the lightest bosons are the superfluid mode H and the kaons K{sup 0} and
Formation of Gapless Phases of $K^0$ Condensed Color-Flavor Locked Superconducting Quark Matter
Electric and color neutral solutions, and the critical conditions for the formation of gapless color superconductors, are investigated in K{sup 0} condensed color-flavor locked quark matter for
Bose?Einstein Condensation in Strong-Coupling Quark Color Superconductor near Flavor SU(3) Limit
Near the flavor SU(3) limit, we propose an analytical description for color-flavor-locked-type Bardeen—Cooper—Schrieffer (BCS) phase in the Nambu Jona—Lasinio (NJL) model. The diquark behaviors in
Bulk viscosity in kaon-condensed color–flavor-locked quark matter
Color–flavor-locked (CFL) quark matter at high densities is a color superconductor, which spontaneously breaks baryon number and chiral symmetry. Its low-energy thermodynamic and transport properties
Shear viscosity from kaon condensation in color-flavor-locked quark matter
We calculate the kaonic contribution to the shear viscosity of quark matter in the kaon-condensed color-flavor-locked phase (CFL-K0). This contribution comes from a light pseudo-Goldstone boson that
Astrophysical implications of gapless color-flavor locked quark matter: A hot water bottle for aging
The gapless color-flavor locked (gCFL) phase is a candidate for the second-densest phase of matter in the QCD phase diagram, making it a plausible constituent of the core of neutron stars. We show
