40. A Characterisation and Reconstruction of Radial Strip Sensors in Preparation for a Higher Radiation Environment in the ATLAS Detector at CERN

Ryan Justin Atkin (University of Cape Town (ZA))

Poster

The upgrade of the Large Hadron Collider (LHC) to the high luminosity LHC (HL-LHC) will result in far more collisions occurring per particle bunch crossing, in turn producing more particles per second. Consequently, the current detectors will need to be upgraded to accommodate for the large increase in radiation and data acquisition as well as a need to improve the tracking efficiency for the...

10. Fake-Rate Determination for the ttH Coupling Measurement with a Signature of Two Same Electric Charge Light Leptons Associated with a Tau Using the ATLAS Detector at the LHC

Poster

After the discovery of a Higgs boson, the measurements of its properties are at the forefront of research. The determination of the associated production of a Higgs boson and a pair of top quarks is of particular importance as the ttH Yukawa coupling is large and can probe for physics beyond the Standard Model. The analysis is based on data taken by the ATLAS experiment recorded from 13 TeV...

13. Search for a Heavy Boson in ZZ→4l with the ATLAS Experiment at the LHC

ATLAS Collaboartion

Poster

This poster presents the search for a heavy boson resonance decaying into a
pair of Z bosons leading to a 4l final state, where l stands for either an
electron or a muon. The search uses proton–proton collision (Run-2) data at a
centre-of-mass energy of 13 TeV collected with the ATLAS detector during 2015
and 2016 at the LHC. This study aims at answering the important question
whether the...

11. Search for non-resonant Higgs boson pair production

Alan Taylor (The University of Edinburgh)

Poster

Higgs boson pair production can be used to understand the Higgs boson self-coupling and also serve as a probe for new physics. This poster presents the search for non-resonant Higgs boson pair production in the bbbb, bbtautau and bbyy final states using upto 36.1fb-1 of proton-proton collisions at sqrt(s)=13 TeV collected by the ATLAS detector. The combination of the three searches is also...
