墨卡托奖学金：QCD和规则是风味物理中与模型无关的强子矩阵元素计算的主要理论工具。该方法依赖于相关函数的微扰计算，并结合真空凝聚密度等普遍的非微扰输入。该计算结果与涉及强子量的现象学参数化相匹配，然后从该过程中提取强子量。墨卡托项目的目标是使用手性微扰理论来改进QCD求和规则中使用的现象学参数化。手性微扰理论是一种以强子为基本实体的有效场论，它非常适合于改进现象学参数化。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门知识。教授职位（NF Khodjamirian）： A. Khodjamirian教授是研究部QCD和规则活动的主要支柱。然而，他将在第二个资助期退休，我们申请提前接替，以确保平稳过渡，保持高水平的专业知识在QCD求和规则的研究单位。项目专题研讨会：研究单位专注于评估强子矩阵元素的非点阵方法。然而，通过在非晶格社区和晶格社区之间交换结果和经验，可以创造出明显的附加价值。出于这个原因，我们计划与专家一起进行QCD晶格计算，计算与风味物理相关的强子矩阵元素。计划在第二个资助期开始时举办第二次研讨会，向对现象学感兴趣的部分社区，特别是向我们的实验同事传播研究小组的成果。协调：为了行政协调，我们申请文秘支持（兼职职位）；科学协调工作将由参与其中一个项目的博士生或博士后承担。

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.
