N-point Statistics of Large-Scale Structure in the Zel'dovich
  Approximation
  Motivated by the results presented in a companion paper, here we give a
simple analytical expression for the matter n-point functions in the Zel'dovich
approximation (ZA) both in real and in redshift space (including the angular
case). We present numerical results for the 2-dimensional redshift-space
correlation function, as well as for the equilateral configuration for the
real-space 3-point function. We compare those to the tree-level results. Our
analysis is easily extendable to include Lagrangian bias, as well as
higher-order perturbative corrections to the ZA. The results should be
especially useful for modelling probes of large-scale structure in the linear
regime, such as the Baryon Acoustic Oscillations. We make the numerical code
used in this paper freely available.
