abstract
Gravitino problem is discussed in detail. We derive an upperbound on the reheating temperature from the constraints of the big-bang nucleosynthesis and the present mass density of the universe. Compared to previous works, we have improve the following three points; (i) the gravitino production cross sections are calculated by taking all the relevant terms in the supergravity lagrangian into account, (ii) high energy photon spectrum is obtained by solving the Boltzmann equations numerically, and (iii) the evolutions of the light elements (D, T, $^3$He, $^4$He) at the temperature lower than $\sim$1MeV are calculated by using modified Kawano's computer code.

An additional scalar field dilutes gravitino freeze-in dark matter for matter-like equations of state, permitting larger reheating temperatures consistent with leptogenesis.
Topological amplitude decomposition of two-body B→B_c B̄_c decays with modeled SU(3) breaking fits 9 measured branching ratios and predicts rates for unmeasured modes, finding 35% SU(3) breaking and sizable W-exchange contributions.
