Abstract
Recently, it has been speculated by several authors that quark matter at large d. and low temp. can become a color superconductor. This prediction relies on the asymptotically free character of the strong interaction, QCD, and on the general property of fermionic systems, for which the Fermi surface is unstable with respect to an attractive interaction among the fermions, however weak. In this work, we studied the effects of finite size on the two-flavor color superconducting state by taking into account three different aspects: the boundary conditions felt by the quark fields, which are now constrained in a finite vol., the exact projection of the BCS state over a definite baryon no. and the projection of the BCS state over a color singlet. These effects were evaluated numerically. [on SciFinder (R)]
