Abstract: In models where dark matter relic abundance is set by standard thermal freeze-out mechanism, perturbative unitarity bounds require its mass to be below few hundreds TeV. We propose a new thermal freeze-out mechanism, resulting in dark matter mass up to roughly a million TeV, without violating unitarity bounds and without modifying the standard cosmological history.
