| dc.description | The cosmological moduli problem has been recently reconsidered. Papers [1,2] show that even heavy moduli (m_ϕ> 10^5 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 10^8 ~ 10^9 GeV. | |
