Abstract There are many extensions of the Standard Model with a dark matter (DM) candidate obtained via the freeze-out mechanism. It can happen that after all experimental and theoretical constraints are taken into account. all parameter points have a relic density below the experimentally measured value. This means that the models solve only partially the DM problem. https://www.roneverhart.com/1619PA8038-Bosch-Table-Saw-Motor-Housing-4000-4100-Replaces-2610996864/
