The Standard Model (SM) cannot be the final theory of elementary interactions because there exist fundamental open problems, such as the identification of dark matter, gaining insight into the hierarchy between the electroweak and Planck scales, or understanding the origin of flavor. There must exist a deeper theory, an extension of the SM and finding it is now the main challenge and the main goal of particle physics.The LHC has opened a new era in the exploration of the fundamental laws of Nature, but there is some confusion at the lack of confirmed discoveries of physics beyond the SM. This joint TUM-Warsaw project is a natural reaction to the results from the LHC, which after its first period of operation found, that the New Physics scale is not in the ballpark of a few hundred of GeV for most models as initially expected but rather shifted into the TeV range or higher. Its main objective is to push the systematic search for the extension of the SM one step further, to theories that are consistent with the present data but can be tested in the experiments of the next decade. Our research program is centered at the interface of collider phenomenology and low-energy precision physics and it aims at the synthesis of theoretical lessons learned from both. Our understanding of the TeV scale is evolving: motivated by new ideas using the frameworks of a pseudo-Goldstone Higgs and supersymmetry, we will pursue models which explain the absence of new particles in the data until now. In the course of the phenomenological exploration, we will develop general tools which allow a broad and precise recasting of LHC results, the interpretation of flavor and CP measurements, and their correlated implications. As a consequence we will be able to probe in the broadest range of ways and with the best tools that we can design. Ultimately we will be in a position to make whatever discoveries Nature places within our reach.

标准模型（SM）不可能是基本相互作用的最终理论，因为还存在一些基本的开放问题，例如暗物质的识别，对电弱和普朗克尺度之间的层次结构的深入了解，或者理解味道的起源。粒子物理学的主要挑战和主要目标是找到一个更深层次的理论，即SM的延伸。LHC开启了探索自然基本定律的新时代，但人们对SM之外的物理学发现缺乏确认感到困惑。TUM华沙联合项目是对LHC结果的自然反应，LHC在第一阶段运行后发现，新物理学尺度并不是最初预期的大多数模型的几百GeV，而是转移到TeV范围或更高。它的主要目标是推动系统的搜索SM的扩展更进一步，与目前的数据一致，但可以在未来十年的实验中进行测试的理论。我们的研究项目集中在对撞机现象学和低能精密物理学的界面上，旨在综合从两者中学到的理论教训。我们对TeV尺度的理解正在发展：受到使用伪戈德斯通希格斯和超对称框架的新想法的激励，我们将追求解释数据中没有新粒子的模型。在现象学探索的过程中，我们将开发通用工具，允许广泛和精确的重铸LHC的结果，味道和CP测量的解释，以及它们的相关影响。因此，我们将能够以最广泛的方式和我们所能设计的最好的工具进行探测。最终，我们将能够做出大自然赋予我们的任何发现。
