The authors provide a state of the art analysis of the effects of long-lived non-Standard Model massive particles, decaying during big-bang nucleosynthesis (BBN), on the primordial abundances of light elements. Besides updated standard BBN reaction rates, additional processes and new numerical algorithms are implemented to discuss also solutions to the Lithium problem and the possible gravitino mass for leptogenesis to work.
