Dark and visible matter with broken R-parity and the axion multiplet
  A small breaking of R-parity reconciles thermal leptogenesis, gravitino dark
matter and primordial nucleosynthesis. We find that the same breaking relaxes
cosmological bounds on the axion multiplet. Naturally expected spectra become
allowed and bounds from late particle decays become so weak that they are
superseded by bounds from non-thermal axion production. In this sense, the
strong CP problem serves as an additional motivation for broken R-parity.
