Measurement of the Weak Mixing Angle and the Spin of the Gluon from Angular Distributions in the Reaction pp → Z/γ* + X → μ+μ- + X with ATLAS
(2013-11-15)
The measurement of the effective weak mixing angle with the ATLAS experiment at the LHC is presented. It is extracted from the forward--backward asymmetry in the polar angle distribution of the muons originating from $Z$ ...
Hybrid Pixel Readout Chip Verification, Characterization and Wafer Level Testing for the ATLAS-ITK Upgrade at the HL-LHC
(2023-07-04)
The HL-LHC upgrade starting in 2026 will provide an opportunity for new high-energy physics experiments, but also present challenges for its tracking detectors, particularly the pixel detectors close to the interaction ...
Development and Characterisation of Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2022-10-07)
With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity increases by a factor of five with respect to its design value from 2027. To keep the detectors at the ...
Towards High Precision Measurements of Higgs Boson Properties in the Di-Tau Decay with the ATLAS Detector
(2025-01-28)
The Standard Model of particle physics (SM) describes the known fundamental particles and their interactions. The model is found to be incomplete with a need for extensions in order to cover all current experimental ...
3D-Silicon and Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2020-10-30)
The future upgrade of the Large Hadron Collider to the High-Luminosity LHC demands new pixel detectors that can operate in environments with exceptionally high radiation. This requires investigations into new radiation-tolerant ...
Measurement of the top-quark mass and the ttZ cross section in ATLAS: the tt dilepton way
(2015-07-07)
A measurement of the top-quark mass and the ttZ cross section is performed using 4.6 fb-1 and 20.3 fb-1 of data from proton-proton collisions collected ...
Characterization and Quality Control of RD53A Readout Chips and Modules for the ATLAS ITk Pixel Detector
(2021-12-16)
In preparation of the upcoming high-luminosity upgrade of the Large Hadron Collider, the detectors of the major high-energy physics experiments at the accelerator facility will be upgraded as well. In case of the ATLAS ...
ATLAS ITk Silicon Strip Detector Performance Studies based on the System Test with Cosmic Muons at DESY
(2024-11-13)
The ATLAS experiment is the world’s largest collider-based particle physics experiment, located at the LHC in Geneva. An upgrade of the LHC will greatly increase the radiation environment and track density in the inner ...
Observation of W → τντ Decays with the ATLAS Experiment
(2011-05-04)
Physics studies of processes with t leptons in the final state, while challenging at hadron colliders, are of great importance at the LHC. The τ leptons provide important signatures in searches for the Higgs boson as well ......
Pixeldetektoren aus Silizium und CVD-Diamant zum Teilchennachweis in ATLAS bei LHC
(2001)
The ATLAS experiment at the future Large Hadron Collider at CERN uses a silicon pixel detector as the innermost tracking device. Measurements characterising the prototype ATLAS pixel readout chip FE-A/C are described and ...
