Mercator Fellowship: QCD sum rules are among the major theoretical tools for the model-independent computation of hadronic matrix elements for flavour physics. The method relies on perturbative calculations of correlation functions combined with universal nonperturbative input such as vacuum-condensate densities. The result of this calculation is matched to the phenomenological parameterization involving the hadronic quantities which are then extracted from this procedure. The objective of the Mercator project is to use chiral perturbation theory to improve the parametrization of the phenomenological parametrization used in the QCD sum rule. Chiral perturbation Theory is an Effective Field Theory working with the Hadrons as basic entities, which makes it well suited to improve the phenomenological parametrization. The projected Fellow Prof. A Petrov is an expert in this field and would nicely complement the expertise of the other participants in the Research Unit. Professorship (NF Khodjamirian): Prof. A. Khodjamirian is the major pillar of the QCD sum rule activities in the Research Unit. However, he will retire in the second funding period, and we apply for an early replacement in order to ensure a smooth transition, keeping up the high level of expertise in QCD sum rules in the Research Unit. Project Specific Workshops: The Research Unit is focused on non-lattice methods for the evaluation of hadronic matrix elements. However, a clear added value is created by an exchange of results and experiences between the non-lattice and lattice communities. For this reason we plan a project specific workshop together with experts performing QCD lattice calculations for hadronic matrix elements relevant in Flavour Physics. A second workshop at the beginning of the second funding period is planned to disseminate the results of the Research Unit in the part of the community interested in phenomenology, in particular to our experimental colleagues. Coordination: For the administrative coordination we apply for secretarial support (half time position); the scientific coordination will be taken over by one of the doctoral student or postdoc working in one of the projects.

墨卡托研究金：QCD求和规则是味物理中强子矩阵元的模型无关计算的主要理论工具之一。该方法依赖于微扰计算的相关函数结合普遍的非微扰输入，如真空冷凝密度。这个计算的结果是匹配的唯象参数化涉及的强子量，然后从这个过程中提取。墨卡托计划的目标是利用手征微扰理论改进QCD求和规则中唯象参数化的参数化。手征微扰理论是一种以强子为基本实体的有效场论，这使得它非常适合于改进唯象参数化。预计的研究员A Petrov教授是这一领域的专家，将很好地补充研究股其他参与者的专业知识。 教授职位（NF Khodjamirian）：A. Khodjamirian是QCD求和规则研究的主要支柱。然而，他将在第二个资助期退休，我们申请提前接替，以确保顺利过渡，保持研究部门在QCD总和规则方面的高水平专业知识。 项目具体研讨会：研究单位的重点是非晶格方法的强子矩阵元素的评价。然而，一个明显的附加值是通过非网格和网格社区之间的结果和经验的交流创造的。为此，我们计划与专家一起进行量子色动力学晶格计算的强子矩阵元素相关的风味物理项目的具体研讨会。计划在第二个资助期开始时举办第二次研讨会，在对现象学感兴趣的社区中传播研究单位的成果，特别是向我们的实验同事。 协调：对于行政协调，我们申请秘书支持（半职）;科学协调将由在其中一个项目中工作的博士生或博士后之一接管。
