Query: Novel Families of Fractional Quantum Hall States: Pairing of Composite
  Fermions   Fractional quantum Hall (FQH) states have recently been observed at
unexpected values of the filling factor nu. Here we interpret these states as a
novel family of FQH states involving pairing correlations rather than Laughlin
correlations among the quasiparticles (QP's). The correlations depend upon the
behavior of the QP-QP pseudopotential V_QP(L'), the interaction energy of a
pair as a function of the pair angular momentum L'. This behavior, known from
numerical studies of small systems, is used to demonstrate that pairing
correlations give rise to FQH states at the experimentally observed values of
nu.
