A note on the primordial abundance of stau NLSPs
arXiv:0808.0829 · doi:10.1088/1475-7516/2008/10/026
Abstract
In scenarios with a gravitino LSP, there exist strong BBN constraints on the abundance of a possible stau NLSP. We find that in settings with substantial left-right mixing of the stau mass eigenstates these constraints can be evaded even for very long-lived staus.
