Phys. Rev. D 70, 094030 (2004) [24 pages]Screening masses in a neutral two-flavor color superconductorReceived 6 September 2004; published 17 November 2004 The Debye and Meissner screening masses of the gluons and the photon in neutral and β-equilibrated dense two-flavor quark matter are calculated. The results are presented in a general form that can be used in gapped as well as gapless color superconducting phases. The results for the magnetic screening masses indicate that the system develops a chromomagnetic instability. Possible consequences of the instability are discussed. © 2004 The American Physical Society URL:
