dc.descriptionIt is pointed out that loop corrections involving heavy quarks and their superpartners can re-introduce a state with 99.5% higgsino purity as a viable cold Dark Matter candidate. Such corrections can increase the mass splitting between the three higgsino-like states of the MSSM by several GeV, which results in a suppression of the co-annihilation rate by a factor of five or more. Related corrections to the couplings of the LSP to $Z$ and Higgs bosons can change the predicted LSP detection rate by two orders of magnitude.
