1. 1. Misalignment effects on the physics performance of the inner tracker upgrade at the ALICE experiment

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Jesper Karlsson Gumprecht; [2024]
   Nyckelord :ALICE; ITS; ITS2; ITS3; O2; O2Physics; Distortion; Misalignment; Alignment; Realignment; Physics and Astronomy;

   Sammanfattning : This thesis deals with the physics performance of an approved inner tracker upgrade of the ALICE experiment involving a novel and ultra-thin silicon detector with a cylindrical geometry. During the thesis work, a method was developed in simulations to induce distortions to the detector’s geometry, and the resulting loss in physics performance was evaluated. LÄS MER

3. 2. MadGraph Implementations of the Chirality-Flow Formalism for QED

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Emil Boman; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. LÄS MER

4. 3. Rejection of the Photon Induced Background in LDMX at 8 GeV

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Erik Wallin; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The Light Dark Matter eXperiment (LDMX) is a proposed fixed target experiment at SLAC's LCLS-II electron beamline that will attempt direct production of sub-GeV dark matter, measurable through a missing momentum and missing energy signature. An initial run of LDMX is planned at 4 GeV beam energy, for which a study on LDMX's capabilities to separate dark matter production events from the standard model background was previously performed.

5. 4. A literature review of FASERν - An emulsion detector for collider neutrinos

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Lisa Andersson Loman; [2021]
   Nyckelord :physics; neutrinos; FASER; Standard Model; Beyond Standard Model; BSM; particles; elementary particles; neutrino cross sections; LHC; FASER nu; particle physics; physics experiment; CERN; long lived particles; Physics and Astronomy;

   Sammanfattning : In 2021, the ForwArd Search ExpeRiment (FASER) will start searching for light and weakly coupled particles 480m from the proton-proton collision point of ATLAS at the Large Hadron Collider (LHC). The FASER main detector will have a sub-detector, FASERν, sensitive to high-energy collider neutrinos of all flavours. LÄS MER

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

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

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

   Sammanfattning : 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.
