Query: New fixed points of the renormalisation group for two-body scattering   We outline a separable matrix ansatz for the potentials in effective field
theories of nonrelativistic two-body systems with short-range interactions. We
use this ansatz to construct new fixed points of the renormalisation-group
equation for these potentials. New fixed points indicate a much richer
structure than previously recognized in the RG flows of simple short-range
potentials.
