1. 1. Optimization and validation of Geant4 detector simulation software for the ATLAS experiment at the LHC

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Einar Elén; [2020]
   Keywords : ATLAS; LHC; Geant4; Compiler optimization; Reproducibility; Physics and Astronomy;

   Abstract : Simulations of large detectors such as the ATLAS detector at the LHC (Large Hadron Collider) are compute-intensive projects, and are according to current internal estimates expected to be consuming 40 % of the total ATLAS CPU resources in 2020, creating a need for software optimization strategies. We investigate build configurations of the Geant4 simulation software to find if a) a performance improvement can be made by switching build configuration and b) if such build configuration switches produce the same physics results.

3. 2. Majorana Neutrinos - Same Sign Di-Muon Investigations in 8 TeV Datasets with the BUMPHUNTER Algorithm

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Einar Elén; [2016]
   Keywords : BUMPHUNTER; Majorana Neutrino; ATLAS; Di-muon; Neutrino; Physics and Astronomy;

   Abstract : A hypertest-algorithm, the BUMPHUNTER, is introduced briefly and tested by probing events containing muons in 8 TeV datasets from the ATLAS detector at the Large Hadron Collider (LHC) at CERN against a background spectrum created by selecting muons from different collisions. The hypertest looked for excesses of same sign di-muon pairs which could indicate the existence of a Majorana neutrino. READ MORE
