The cosmological moduli problem has been recently reconsidered. Papers [1, 2] show that even heavy moduli (m<sub>φ</sub>>10<sup>5</sup> GeV) can be a problem for cosmology if a branching ratio of the modulus into gravitini is large. In this paper, we discuss the tachyonic decay of moduli into the Standard Model's degrees of freedom, e.g. Higgs particles, as a resolution to the moduli-induced gravitino problem. Rough estimates on model dependent parameters set a lower bound on the allowed moduli at around 10<sup>8</sup> ∼ 10<sup>9</sup> GeV. |
