Abstract

We calculate the Meissner masses of gluons in neutral three-flavor colorsuperconducting matter for finite strange quark mass. In the CFL phase theeissner masses are slowly varying function of the strange quark mass. For largestrange quark mass, in the so called gCFL phase, the Meissner masses of gluonswith colors $a=1,2,3$ and 8 become imaginary, indicating an instability.
