Description
In the MSSM, light scalar top quarks are well motivated and
often contribute significantly to the neutralino dark matter
relic density. We present a new precision calculation of
stop annihilation into heavy quarks at next-to-leading order
of SUSY-QCD and with Coulomb resummation effects and discuss
the size and uncertainty of these corrections with respect
to the experimental measurement of the relic density.
