Effective field theory of the Majorana dark matter

【摘要】 We revisit the thermal Majorana dark matter from the viewpoint of the minimal effective field theory. In this framework, analytical results for dark matter annihilation into Standard Model particles are derived. The dark matter parameter space, subject to the latest LUX, Panda X-Ⅱ and Xenon-1 T limits, is presented in a model-independent way. Applications to the singlet-doublet and MSSM are presented.更多还原
