Top quark pair production in pp collisions.
The top quark was discovered and first
studied at the Fermilab
Tevatron. During the first data-taking run of the LHC (2009-2012), the group participated
in a new era of top quark physics:
- Top quark decays were one of the most important
calibration signal during the commissioning of the LHC
- The large number of top quarks produced at the LHC allow
for precision measurements of the top quark production rate.
- The large top quark mass makes the top sector a prime area
for the search for "new physics" at the LHC.
ATLAS silicon pixel detector.
At the heart of the ATLAS experiment, novel
silicon detectors provide the precision tracking and vertexing
necessary for top quark physics. The group was working on
- Commissioning and operation of the new ATLAS silicon
- Research and development towards new and improved
silicon strip detectors for the high-luminosity upgrade of the LHC (HL-LHC),
currently planned for 2022.
