Modeling the large-scale redshift-space 3-point correlation function of
  galaxies
  We present a configuration-space model of the large-scale galaxy 3-point
correlation function (3PCF) based on leading-order perturbation theory and
including redshift space distortions (RSD). This model should be useful in
extracting distance-scale information from the 3PCF via the Baryon Acoustic
Oscillation (BAO) method. We include the first redshift-space treatment of
biasing by the baryon-dark matter relative velocity. Overall, on large scales
the effect of RSD is primarily a renormalization of the 3PCF that is roughly
independent of both physical scale and triangle opening angle; for our adopted
$\Omega_{\rm m}$ and bias values, the rescaling is a factor of $\sim 1.8$. We
also present an efficient scheme for computing 3PCF predictions from our model,
important for allowing fast exploration of the space of cosmological parameters
in future analyses.
