Welcome
The Collaborative Research Center Particle Physics Phenomenology after the Higgs Discovery is a joint venture of theoretical particle physicists from the 
Karlsruhe Institute of Technology, 
RWTH Aachen University, the 
University of Siegen, and 
Heidelberg University. It is supported by the German Research Foundation
(DFG).
Particle physics has long established itself as an important research discipline focused on understanding nature at a fundamental level. The current knowledge is summarized in a theory called the Standard Model of particle physics that describes strong and electroweak interactions. The discovery of the Higgs boson in 2012 formally completes the Standard Model and provides us with a consistent mathematical framework that can be used to describe nature in fine detail. However, several aspects of the Standard Model force us to raise questions about the foundations of this theory. Many proposed answers to these questions suggest that the Standard Model is a low-energy approximation to a much more fundamental theory that we strive to discover.
Scientists of the CRC will conduct research in the phenomenology of elementary particles, focusing in particular on physics related to the Higgs boson, the physics of top quarks, electroweak gauge bosons, jets, and dark matter, as well as flavor physics. Our goal is to develop novel concepts and methodologies to search for physics beyond the Standard Model through precise measurements at the LHC, at flavor factories and elsewhere.
Open positionsThe CRC has openings for Ph.D. positions. More information can be found here, or directly contact the principal investigators. |

The main goal of the event is to discuss new ideas and research directions in Higgs and top physics, as well as to explore potential flavor studies at future colliders. Another focus will be the interplay between high-energy physics and quantum information theory. Alongside the scientific presentations, we expect active discussions on these topics to foster new collaborations with the research groups in Siegen, especially in preparation for the third funding period of the CRC. More information can be found here. (posted on: 30.04.2025)
In the new episode Lindy Hop with Flavor physics, Gilberto Tetlalmatzi-Xolocotzi (Siegen U) tells us about studying physics in Mexico City, dancing Lindy Hop in Amsterdam, and how B-physics wins over string theory.

The HH workshop will provide the opportunity to review the latest theoretical results on Higgs boson pair production and on searches for new physics in the scalar sector, with final results from LHC Run 2, results from the ongoing LHC Run 3, and the prospects and potential of the di-Higgs searches at the future colliders. Several members of the CRC will present their latest results. More information can be found here (posted on: 05.05.2025)
The Young Scientists Meeting is a 2.5 days meeting for all members of the Collaborative Research Center TRR 257. The scientific talks will be presented by early career scientists (PhD students or PostDocs) and they will focus on the various projects of our CRC. This will give all participants the opportunity to get updated about progress in these projects. It also allows the speakers to present their research in front of a large audience. More information can be found here. (posted on: 06.05.2025)
