Chromomagnetic stability of the CFL phase with a meson current
arXiv:hep-ph/0608249 · doi:10.1016/j.nuclphysa.2006.11.066
Abstract
We show that the color-flavor locked (CFL) phase of dense quark matter is unstable with respect to the formation of a Goldstone boson current in the vicinity of the point . In this Goldstone boson current phase all components of the magnetic screening mass are real.
