Query: Probing the Nucleon's Transversity Via Two-Meson Production in Polarized
  Nucleon-Nucleon Collisions   We explore the possibility of probing the nucleon's transversity distribution
$\delta q(x)$ through the final state interaction between two mesons
($\pi^+\pi^-$, $\pi K$, or $K\bar K$) produced in transversely polarized
nucleon-nucleon collisions. We present a single spin asymmetry and estimate its
magnitude under some assumptions for the transversity distribution function and
the unknown interference fragmentation function.
