Yangian Symmetry in Quantum Gauge Field Theory
Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 01/2017  09/2020
Financer: DFG: SachbeihilfeOur understanding of nature at its deepest level is governed by symmetries. This proposal aims at studying hidden symmetries in quantum field theory going beyond the established spacetime symmetries of the Poincare group and its supersymmetric or co ...

Lacker, Heiko, Prof. Dr. (Experimental Physics / Elementary Particles Physics II)
Duration of Project: 07/2015  12/2018
Financer: BMBFR&D work for the construction of 500 detector modules in one endcap of the silicon strip detector of the future ATLAS detector for the highluminosity LHC. In particular: characterization of Hamamatsu sensors, development of tools to build
modules o ...Topquark physics at colliders
Uwer, Peter, Prof. Dr. rer. nat. (Theoretical Physics / Phenomenology of Elementary Particles beyond the Standard Model)
Duration of Project: 01/2009  12/2014
Financer: DFG: Sonderforschungsbereich  BeteiligungenThe topquark, the heaviest known elementary particle, is an excellent probe of the fundamental interactions at (sub)attometer distances. Theoretical investigations of the production and decay of these quarks are essential for the analysis of the cor ...
RTG 2575/1: Rethinking Quantum Field Theory
Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 04/2020  09/2024
Financer: DFG: GraduiertenkollegsRecent findings have revealed that the Standard Model of particle physics – which brings together the current understanding of the physics of elementary particles in a quantum field theory – requires rethinking. Using a broad research approach, the R ...
RTG 1504/1: Mass, Spectrum, Symmetry: Particle Physics in the Era of the Large Hadron Collider
Plefka, Jan, Prof. Dr. (Theoretical Physics / Quantum Field Theory beyond the Standard Model and String Theory)
Duration of Project: 04/2009  12/2013
Financer: DFG: GraduiertenkollegsThe standard model of elementary particle physics summarizes our theoretical understanding of the nature of elementary particles and has been formidably confirmed by experiment in the last decades. It is nevertheless clear that the standard model onl ...

Lacker, Heiko, Prof. Dr. (Experimental Physics / Elementary Particles Physics II)
Duration of Project: 01/2017  12/2019
Financer: German Israel FoundationSearch for longlived particles, in particular, sterile neutrinos with the ATLAS detector using displaced vertices.
Precision analysis of data concerning a fourth fermion generation with CKMfitter
Lacker, Heiko, Prof. Dr. (Experimental Physics / Elementary Particles Physics II)
Duration of Project: 10/2010  06/2014
Financer: DFG: SachbeihilfeConstraints on parameters for a fourth generation of fermions with the Standard Model of Particle Physics. The data of the LargeHadron Collider at CERN on the production and decay channels of Higgs bosons allowed us to exclude a 4. fermion generatio ...

Duration of Project: 01/2009  12/2014
Financer: Mischfinanzierung (Schwerpunkt Bund)Physics at the Terascale: Physics Analysis, Grid Computing, Detector Physics and Accelerator Physics
Research in particle physics is motivated by the goal of attaining a fundamental description of the laws of physics, such as explaining the origi ... Phenomenological studies of topquark properties at hadron collider
Uwer, Peter, Prof. Dr. rer. nat. (Theoretical Physics / Phenomenology of Elementary Particles beyond the Standard Model)
Duration of Project: 07/2012  06/2015
Financer: BMBFThe main goal of the project is to improve our current understanding of topquark properties using experimental input obtained in hadronic collisions. Topquark physics is one of the central research topics at the Large Hadron Collider (LHC). Since t ...
Numerical approaches for twoloop amplitudes
Schulze, Markus, Dr. (Theoretical Physics / Phenomenology of Elementary Particles beyond the Standard Model)
Duration of Project: 11/2017  10/2019
Financer: DFG: SachbeihilfeThe project concerns developing a fully numerical approach to twoloop amplitudes in QCD. The method is expected to enable precision calculations which are currently unfeasible with conventional analytic solutions, but urgently required for LHC pheno ...
