摘要：

We consider pairing in a dilute system of fermions with a short-range interaction. While the theory is ill-defined for a contact interaction, the BCS equations can be solved in the leading order of low-energy effective held theory. The integrals are evaluated with the dimensional regularization technique. giving analytic formulas relating the pairing gap, the density, and the energy density to the two-particle scattering length.
