Welcome
I am a permanent scientific staff member in the
Experimental Particle Physics group of
Prof. Buchholz
within the Department of Physics
at the University of Siegen, Germany.
Research Interests
- ATLAS
-
ATLAS is one of the four major experiments at the Large Hadron
Collider (LHC) at CERN, the European Particle Physics Laboratory
near Geneva.
As a member of the ATLAS collaboration
I am involved in the following activities:
- Construction and operation of the ATLAS pixel detector.
We have assembled and tested about 330 modules for
this detector in our local labs.
- Preparation of data analyses involving decays of
B-mesons (B-physics). Our group is studying
the measurement of Bs0
oscillations at ATLAS using
the Bs0 →
Ds-a1+
in close collaboration with the particle physics
group at the University of Innsbruck
(Bs0 →
Ds-π+ channel)
and prepares a measurement of the b cross section
at large values of transverse momentum. The later
makes use of our expertise in b-tagging tools.
- Preparation of data analysis tools for tagging of
jets containing B-mesons ("b-tagging").
- HEP-CG
-
Distributed computing on the Worldwide LHC Computing
Grid (WLCG) is essential for being able to analyze
the amount of data expected from the LHC experiments.
As part of the German e-Science initiative D-Grid our group
is member of the High Energy Physics Community Grid (HEP-CG)
project. In collaboration with the group of Prof.
Wismüller of the Department for
Electrical Engineering and Informatics
and the Center of Information and Media Technology (ZIMT)
a Result Monitoring and Online Steering Tool (RMOST) is
being developed. Our group also maintains a local
Grid computing installation as part of the WLCG.
- LCTPC
-
The next worldwide project in accellerator-based particle
physics will most likely be an International Linear Collider
(ILC). As part of the Helmholtz Alliance "Physics on the
the Terascale" and being a partner in the EUDET program,
our group is involved in the development of a
Time Projection Chamber (TPC) for an ILC experiment.
We are investigating read-out options involving GEM foils
for the gas amplification with a local test chamber.
