Our group performs experimental studies on the basic symmetries of the "Standard Model of Particle Physics", which govern the fundamental interactions of particles. Closely related we work on the theoretical simulation of LHC collisions.
The Higgs Field as Damper for Scattering-Experiments at CERN
To study the Standard Model, we investigate one of the rarest but most important processes at the Large Hadron Collider (LHC) at CERN, the scattering of W and Z-particles from one another.
To observe this, two quarks in the proton-proton collisions at the LHC have to radiate one W or Z, each, in coincidence. These then must approach each other to less than 1/1000 of a proton diameter.
The Brout-Englert-Higgs field plays a crucial "damping" role in this scattering process, which thus also gives insight into the properties of the Higgs boson.
In our Research on W- and Z-Scattering at the ATLAS Experiment within the framework of the German research structure FSP-ATLAS, we not only test the damping contribution of Higgs particles, but are for the first time investigating the previously unobserved "Quartic Vertex" in the interaction of four weak bosons.
Find out more on our Research page and in this ATLAS Blog.
Theoretical simulation of LHC collisions with Sherpa
Our group is also working at the interface between experiment and theory for LHC physics and has a particular focus on QCD Monte Carlo simulations and ATLAS measurements sensitive to their modelling aspects. To that end we are activelz contribution to the development of the simulation program Sherpa.
