In order to withstand the high radiation doses at the upcoming High Luminosity-LHC, many components of the ATLAS particle detector need to be upgraded. As a result, my work focuses on the upgrade of the electronic calibration boards for the ATLAS liquid argon electromagnetic calorimeter. In particular, I have investigated the effects of radiation on a new calibration chip prototype, as well as analysed sources of non-uniformity for the first calibration board prototype. These studies will help design and test the final calibration board for the HL-LHC.
The second part of my project deals with the analysis of electroweak production of Zy+2 jets. This study provides the means to test the Standard Model predictions as well as help extract constraints on anomalous couplings that could hint at new physics. Last year, the ATLAS collaboration made public the first fiducial cross section results for this process using data recorded by the detector in 2015-2018. My experimental focus is to measure differential production cross sections of the process, based on the same data set and analysis, and eventually interpret the results in an Effective Field Theory framework.
