| Description: |
Analysis of data from the ATLAS experiment at the LHC has been a research focus in the Department of Physics at Bellarmine University (BU). At BU, analysis has largely been focused on Z boson decays and searching for evidence of a Z’ (Z Prime) boson. The data are stored in the form of .xml files, with one file representing one collision event inside the ATLAS detector. Previous analyses have been conducted on an event-by-event basis, using the Hypatia software package. While this allows for high-quality visualization and effective event analysis, it is highly time-consuming. I propose and implement a piece of software that partially automates this type of analysis by applying filter parameters (cuts) programmatically. It looks for both the e+e- and μ+μ- decay modes. Cuts implemented primarily include transverse momentum: pt > 10 GeV/c for the muon decay mode and pt > 20 GeV/c for the electron decay mode. The program takes as input a directory containing data files and outputs a list of the names of files likely to contain Z (or Z’) boson decays, i.e., lists events that meet filter criteria. Identified events can then be analyzed more quickly using previous methods. |
