Краткий обзор статьи: We show that the cosmological moduli problem is solved, without relying on huge late-time entropy production, if the universal cutoff scale of the theory is a few orders of magnitude smaller than the Planck scale. We obtain a general estimate of the modulus abundance in terms of the inflationary scale and the reheating temperature, and find in particular that the reheating temperature can be high enough for the non-thermal leptogenesis to work.
