Description
The standard WIMP freeze-out analysis, based on Boltzmann equations,
contains unknown theoretical uncertainties, which may start to matter
now that many benchmark scenarios are strongly constrained by data.
In this talk a few issues which are not always included in
phenomenological analyses are elaborated upon. In particular the
potential importance of strongly interacting bound states (e.g. of
gluinos) is re-evaluated. The bound states are shown to
significantly boost the co-annihilation rate with respect to a
Sommerfeld-enhanced analysis, thereby perhaps helping to avoid overclosure.
