Query: Chromomagnetic stability of the CFL phase with a meson current   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 $m_s^2=2\mu\Delta$. In this Goldstone boson current phase
all components of the magnetic screening mass are real.
