Query: Possible Anti-Pfaffian Pairing of Composite Fermions in the Lowest
  Landau Level   We predict that an incompressible fractional quantum Hall state is likely to
form at $\nu=3/8$ as a result of a chiral p-wave pairing of fully spin
polarized composite fermions carrying four quantized vortices, and that the
pairing is of the Anti-Pfaffian kind. Possible experimental ramifications are
discussed.
