Gluons, tadpoles, and color neutrality in a two-flavor color superconductor
نویسندگان
چکیده
Considering cold, dense quark matter with two massless quark flavors, we demonstrate how, in a self-consistent calculation in the framework of QCD, the condensation of Cooper pairs induces a non-vanishing background color field. This background color field has precisely the right magnitude to cancel tadpole contributions and thus ensures overall color neutrality of the two-flavor color superconductor.

The Meissner Effect in a Two Flavor Loff Color Superconductor
We calculate the magnetic polarization tensor of the photon and of the gluons in a two flavor color superconductor with a LOFF pairing that consists of a single plane wave. We show that at zero temperature and within the range of the values of the Fermi sea displacement that favors the LOFF state, all the eigenvalues of the magnetic polarization tensor are non-negative. Therefore the chromomagn...
متن کاملMixing and Screening of Photons and Gluons in a Color Superconductor
We calculate the Debye and Meissner masses of photons and gluons for a spin-one color superconductor in the polar and color-spin-locked phases as well as for a spin-zero color superconductor in the 2SC and color-flavor-locked phases. A general derivation for photon-gluon mixing is provided in terms of the QCD partition function. We show qualitatively and quantitatively which of the gauge bosons...
متن کاملTwo flavor color superconductivity and compact stars
At large baryon density, quantum chromodynamics (QCD) becomes a weakly interacting theory of quarks and gluons [ 1]. Because of an attractive interaction between quarks, the ground state of such quark matter is a color superconductor [ 2, 3, 4]. At asymptotic densities, quark matter was studied from first principles in Refs. [ 5, 6, 7, 8]. Unfortunately, these studies are not very reliable quan...
متن کاملChromomagnetic Instability and Gluonic Phase *
It has been suggested that quark matter might exist inside central regions of compact stars. At sufficiently high baryon density, cold quark matter is expected to be in a color superconducting (CSC) state. This is one of the reasons why the color superconductivity has been intensively studied. Bulk matter in the compact stars must be in β-equilibrium and be electrically and color neutral. The e...

We have calculated the polarization tensor Π ab (P ), a, b = 1, . . . , 8, γ, for gluons and photons in different colorsuperconducting phases. We have explicitly computed its zero-energy, low-momentum limit for the two-flavor color superconducting (2SC), color-flavor-locking (CFL), polar, and color-spin-locking (CSL) phases, which yield the Debye and Meissner masses. These masses determine the ...
