  1. 26. Deep Autoencoders for Compression in High Energy Physics

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

    Author : Eric Wulff; [2020]
    Keywords : ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; high energy physics; data compression; Physics and Astronomy;

    Abstract : Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. READ MORE

  3. 27. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS

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

    Author : Alexander Ekman; [2019]
    Keywords : kaon; neutral kaon; K^0_L; K_Long; klong; single-particle response; response; detector response; calorimeter; ATLAS; CERN; jets; trigger level analysis; TLA; physics list; Monte Carlo; MC; Physics and Astronomy;

    Abstract : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. READ MORE

  4. 28. Studies of Possible QGP Estimators in proton-proton Collisions

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

    Author : Anna Önnerstad; [2019]
    Keywords : Physics and Astronomy;

    Abstract : This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator called Mid-Forward. READ MORE

  5. 29. Omega Baryon Production as a Function of Multiplicity in Proton-Proton Collisions at $\sqrt{s}=13$ TeV

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

    Author : Lisa Vergara Urrutia; [2019]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis the production of the $\Omega^-$ and $\Omega^+$ baryons, in proton-proton collisions at $\sqrt{s}=13$ TeV, is analyzed as a function of charged-particle multiplicity. The events analyzed were recorded by the ALICE detector, at the LHC. READ MORE

  6. 30. PARTON SHOWER UNCERTAINTIES ON THE TOP MASS

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hristina Georgieva Hristova; [2019]
    Keywords : top quark mass; uncertainty; Lund Monte Carlo; Pythia; Physics and Astronomy;

    Abstract : The non-Abelian QCD nature allows for pp collisions to contain gluon emissions off quarks as well as gluon branchings into further gluons — a structure that can be described by the parton shower model. In this project we present the results of the impact the shower has on the reconstruction of the W-boson and top quark masses using Pythia, the Lund Monte Carlo event generator. READ MORE
