GRK 2149: Strong and Weak Interactions - from Hadrons to Dark Matter

在研究培训组“强和弱相互作用-从强子到暗物质”的理论和实验核，粒子和天体粒子物理学家一起研究粒子物理学的独特方式高度热门的方面。由于研究培训小组的第一个供资期，这种合作已经得到明显加强。因此，第二个资助期的策略严格地建立在第一阶段的研究和资格认证计划的经验基础上。在强相互作用领域，提出的问题的特点是高度复杂，方法通过精确的测量和预测，在这一领域的密切联系的例子是冷和密核物质中的部分子分布和热夸克-胶子等离子体和介子的性质。它们现在被重夸克的束缚态（夸克偶素），不仅在LHC上的分析，特别是ALICE，而且还有BESIII，统计模型以及微扰和非微扰理论方法之间的更紧密联系所补充。在弱相互作用领域，问题和模型更具投机性，但选择它们的动机和高发现潜力。在标准模型之外寻找新物理的过程中，暗物质、中微子和味道破坏特别交织在一起。这一领域的新发展包括：委托进行中微子质量实验KATRIN，以前所未有的精度测量β衰变谱;世界领先的用XENON 1 T/nT直接搜索暗物质的实验;中微子观测站IceCube，它目前正在加强与天体物理学的联系;以及在这一领域将微扰和非微扰理论方面结合起来。研究的问题现在已经在做，将来也肯定会吸引优秀的学生，也因为这些项目的动机不仅来自核和粒子物理学，而且来自天体物理学和宇宙学。对于我们的博士论文组合，物理学不同分支的接口以及理论家和实验家之间的密切合作至关重要。

In the Research Training Group “Strong and Weak Interactions – from Hadrons to DarkMatter” theoretical and experimental nuclear, particle, and astroparticle physicists investigatetogether in a unique way highly topical aspects of particle physics. This cooperationhas already been visibly strengthened owing to the first funding period of the ResearchTraining Group. The strategy for the second funding period therefore builds stringentlyon the experience of the first phase both in the research and in the qualificationprogramme. In the area of strong interactions, the posed questions are characterisedby their high complexity, the methods through precision measurements and predictions.Examples of the close connection in this area are parton distributions in cold and densenuclear matter and the properties of the hot quark-gluon plasma and of mesons. Theyare now complemented by bound states of heavy quarks (quarkonia), analyses not onlyat and for the LHC, especially with ALICE, but also with BESIII, and statistical models aswell as even closer ties between perturbative and non-perturbative theoretical methods.In the field of weak interactions, the questions and models are more speculative, butselected for their motivation and high discovery potential. In the search for new physicsbeyond the Standard Model, dark matter, neutrinos and flavour violation are particularlyintertwined. New developments in this area concern the commissioning of the neutrinomass experiment KATRIN for measurements of the beta decay spectrum with previouslyunattained precision, the world’s leading direct search for dark matter with XENON1T/nT, the neutrino observatory IceCube, which is now strengthening the link to astrophysics,as well as the combination of perturbative and non-perturbative theoretical aspects alsoin this area. The investigated problems do already now and will certainly also in the futureattract excellent students, also because the motivations of these projects not onlycome from nuclear and particle physics, but also from astrophysics and cosmology. Forour portfolio of doctoral theses, the interfaces of different branches of physics and theclose cooperation among theorists and experimentalists are of crucial relevance.
