  text: We propose a possible realization of the overscreened Kondo impurity problem
    by a magnetic s=1/2 impurity embedded in a two-dimensional S=1 U(1) spin liquid
    with a Fermi surface. This problem contains an interesting interplay between non-Fermi-liquid
    behavior induced by a U(1) gauge field coupled to fermions and a non-Fermi-liquid
    fixed point in the overscreened Kondo problem. Using a large-N expansion together
    with an expansion in the dynamical exponent of the gauge field, we find that the
    coupling to the gauge field leads to weak but observable changes in the physical
    properties of the system at the overscreened Kondo fixed point. We discuss the
    extrapolation of this result to a physical case and argue that the realization
    of overscreened Kondo physics could lead to observations of effects due to gauge
    fields.
