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.roamingfreesims.com/product-category/philips-hid-pv-s-sdw-tg/
