  The influence of short-range correlations on the spectral distribution of
neutrons is incorporated in the solution of the gap equation for the
${}^3P_2-{}^3F_2$ coupled channel in pure neutron matter. This effect is
studied for different realistic interactions including one based on chiral
perturbation theory. The gap in this channel vanishes at all relevant densities
due to the treatment of these correlations. We also consider the effect of
long-range correlations by including polarization terms in addition to the bare
interaction which allow the neutrons to exchange density and spin fluctuations
governed by the strength of Landau parameters allowed to have reasonable values
consistent with the available literature. Preliminary results indicate that
reasonable values of these parameters do not generate a gap in the
${}^3P_2-{}^3F_2$ coupled channel either for all three realistic interactions
although the pairing interaction becomes slightly more attractive.
