Contact interactions and top-philic scalar dark matter

Abstract We investigate the phenomenology of a scalar top-philic dark matter candidate when adding a dimension-five contact interaction term, chiggate.com as motivated by possible underlying extensions of the Standard Model such as composite Higgs models.We show that the presence of contact interactions can have a major impact read more on the dark matter relic density as well as on its direct and indirect detection prospects, while the collider phenomenology of the model is unaffected.This underlines the complementarity of collider and cosmological constraints on dark matter models.
