    "abstract": "We study in detail the dependence of the 1S0 superfluid pairing gap on\nnuclear interactions and on charge-independence breaking at the BCS level.\nStarting from chiral effective-field theory and conventional nucleon-nucleon\n(NN) interactions, we use the renormalization group to generate low-momentum\ninteractions V_{low k} with sharp and smooth regulators. The resulting BCS gaps\nare well constrained by the NN scattering phase shifts, and the cutoff\ndependence is very weak for sharp or sufficiently narrow smooth regulators with\ncutoffs Lambda \u003e 1.6 fm^{-1}. It is therefore likely that the effect of\nthree-nucleon interactions on 1S0 superfluidity is small at the BCS level. The\ncharge dependence of nuclear interactions has a 10% effect on the pairing gap.",
