Towards the Identification of Dark Matter

暗物质（DM）占宇宙中所有现存物质的85%，探测和识别暗物质构成了现代物理学的一个关键挑战。事实上，支持大量这种新粒子存在的证据可能是标准模型之外的新物理学最清晰的线索之一。暗物质可以直接（通过探测器内部原子核的弹性散射）、间接（试图观察其湮灭产物）或在粒子对撞机中搜索。天体粒子物理实验的显著成果和大型强子对撞机（LHC）的开始为从互补的角度解决这个问题提供了独特的可能性。完全理解DM的本质和新物理学的正确模型只能来自对来自不同实验的信号的综合研究。这定义了项目将在其中开发的框架。我们将研究直接和间接探测实验中假设未来数据的DM参数重建，利用不同实验技术的组合并研究影响不确定性（例如天体物理和核）。在直接探测实验的特殊情况下，我们将考虑最一般的有效拉格朗日形式来描述dm -核相互作用。我们还将研究年度调制对这些新运营商的影响。这些实验的真实数据有望在未来几年得到。我们将尝试用DM的粒子物理模型来解释它，也试图解决与大型强子对撞机结果的兼容性。

The detection and identification of the dark matter (DM), which makes up about 85% of all existing matter in the Universe, constitutes a key challenge in modern Physics. In fact, the evidence supporting the existence of large amounts of this new kind of particle is possibly one of the clearest hints for new physics beyond the Standard Model. Dark matter can be searched for directly (through its elastic scattering with nuclei inside a detector), indirectly (attempting to observe its annihilation products) or in particle colliders. The remarkable efforts in Astroparticle Physics experiments and the onset of the Large Hadron Collider (LHC) offer the unique possibility of attacking this problem from complementary perspectives. A complete understanding of the nature of the DM and the correct model for new Physics can only come from the combined study of signals originating from the different kinds of experiments. This defines the framework in which the project will be developed.We will investigate the reconstruction of DM parameters from hypothetical future data in direct and indirect detection experiments, exploiting the combination of different experimental techniques and investigating the effect uncertainties (e.g., astrophysical and nuclear). In the particular case of direct detection experiments, we will consider the most general Effective Lagrangian formalism to describe the DM-nucleus interaction. We will also study the effect of annual modulation on these new operators. Real data from these experiments is expected in the coming years. We will attempt to interpret it in terms of particle physics models for DM, trying also to address compatibility with results at the Large Hadron Collider.
