Color superconductivity and nondecoupling phenomena in (2+1)-dimensional QCD - art. no. 025005

The possibility of generating a color superconducting state in (2 + 1)-dime nsional QCD is analyzed. The gap equation in the leading, hard-dense loop i mproved, one-gluon exchange approximation is derived and solved. The magnit ude of the order parameter is proportional to a power of the coupling const ant. For an asymptoti cally large chemical potential, a qualitatively new [ with respect to the (3 + 1)-dimensional case] phenomenon of nondecoupling o f the fermion pairing dynamics from the infrared one is revealed and discus sed.
