.... equations [10] In such context, as we shall see in this paper, the relaxation of the bound has two important consequences: the allowed range of dilaton masses may become compatible with a) model of supersymmetry breaking able to provide a natural resolution of the gauge hierarchy problem [11], and with b) the possibility that our universe is presently dominated by a relic background of dilaton dark matter. It should be mentioned that a growing scalar perturbation spectrum is also predicted by the hybrid inflation model proposed by Linde [12] and recently generalized to the class of ....
.... the condition should be satisfied [5 7] Such a condition implies 14 GeV (11) This last requirement could be alleviated, however, in the case of low energy (electro weak, for instance) baryogenesis; in particular, in the case of baryogenesis associated to the dilaton decay itself [7,11], occuring at scales not much distant from nucleosynthesis. These are the standard arguments, leading to bounds on m which are independent of the inflation scale H 1 , and which are crucially grounded on the assumption that the asymptotic value OE 1 , approached by OE during its evolution for H ....

.... problem cannot be evaded by a long period of ordinary inflation as the latter regenerates via long wave quantum fluctuations (which are important for OE if m OE H I ) an unacceptably large VEV for OE [127] The Polonyi problem is a serious difficulty for all moduli because, as stressed in [130] [131], 132] 118] current SUSY breaking lore suggests that they (as well as their fermionic partners) acquire masses of order m OE m 3=2 1 TeV, which is uncomfortably below the 30 TeV limit mentioned above. In essence, this mass estimate follows from V (OE) m 4 SUSY v(OE= mP ) m 2 3=2 ....

....the source of gaugino masses in many supergravity models is completely different from the source of scalar masses, since the former arise from dimension 3 SUSYbreaking operators. In some such models, such as those in which SUSY is broken in the hidden sector and there are no gauge singlets [4 6], the dimension 3 SUSY breaking terms are either absent or suppressed by a factor of the Planck mass. Thus, in these models, the gluino and photino 1 are massless at tree level. Masses will be generated by radiative corrections; these were calculated by Farrar and Masiero [7] who found that as ....
