An analytic halo approach to the bispectrum of galaxies in redshift
  space
  We present an analytic formula for the galaxy bispectrum in redshift space on
the basis of the halo approach description with the halo occupation
distribution of central galaxies and satellite galaxies. This work is an
extension of a previous work on the galaxy power spectrum, which illuminated
the significant contribution of satellite galaxies to the higher multipole
spectrum through the non-linear redshift space distortions of their random
motions. Behaviors of the multipoles of the bispectrum are compared with
results of numerical simulations assuming a halo occupation distribution of the
LOWZ sample of the SDSS-III BOSS survey. Also presented are analytic
approximate formulas for the multipoles of the bispectrum, which is useful to
understanding their characteristic properties. We demonstrate that the Fingers
of God effect is quite important for the higher multipoles of the bispectrum in
redshift space, depending on the halo occupation distribution parameters.
