摘要：

We obtain an improved cosmological mass bound of the axino (fermionic partner of the axion), and observe that the axion energy crisis problem is modified for F(a) greater-than-or-equal-to 10(12) GeV, from the consideration of the photon reheating due to decay of the saxino (scalar partner of the axion) in supergravity models.
