Query: Charge and Statistics of Quasiholes in Pfaffian States of Composite
  Fermion Excitations   The charge of quasiparticles in Pfaffian states of composite fermion
excitations (the presence of which is indicated by recent experiments) is
found. At the filling fraction of the Pfaffian state $\nu=p/q$ (of the lowest
Landau level) the charge is $\pm e/(2q)$. As in the case of the Pfaffian state
of electrons the statistics of $N_{qh}$ quasiholes in the Pfaffian state
corresponds to the spinor representation of $U(1)\times SO(2N_{qh})$ (the
continuous extension of the braid group). Here U(1) is given by the phase
factor $e^{i({1/8}+\frac{1}{4m})\pi}$ with $m=1+\alpha$, $\alpha$ -- the
exclusion statistics parameter of Jain quasiparticles. The possiblity of
Read-Rezayi states of Jain quasiparticles is also discussed.
