  1. 21. The impact of initial state radiation on jets from PbPb collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Hilmi Kycyku; [2021]
    Keywords : heavy-ion physics; QGP; quark-gluon plasma; kvark-gluon plasma; initial state radiation; jets; medium response; Physics and Astronomy;

    Abstract : This thesis presents the study of how initial state radiation impacts jets produced in pp and PbPb collisions, by investigating the transverse momentum spectra, the rapidity spectra and the differential jet shape. This is done for central collisions with nucleon-nucleom COM energy 2.76 TeV and 5.02 TeV. READ MORE

  4. 23. Using Neural Networks to Probe the Parameter Space of a 3HDM with a U(1) times Z2 Flavor Symmetry

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ludvig Siwe; [2020]
    Keywords : Three Higgs Doublet Model; 3HDM; Machine Learning; Neural Network; Genetic Algorithm; Physics and Astronomy;

    Abstract : Probing the physical regions in large parameter spaces of typical Standard Model (SM) extensions can be a very difficult computational task. In this thesis project, a new framework has been developed that utilises well-known Machine Learning (ML) techniques in the form of neural networks trained by a genetic algorithm. READ MORE

  5. 24. Investigating RT using two-particle angular correlations in proton-proton collisions

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

    Author : Dilan Chroscik; [2020]
    Keywords : particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

    Abstract : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. READ MORE

  6. 25. Phenomenology of Exotic Decays of Vector-Like Quark X5/3 into Doubly-Charged ScalarXinto Doubly-Charged Scalar

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakub Salko; [2020]
    Keywords : ;

    Abstract : Searches for the Vector-Like Quarks usually look for their signatures assuming they decay purely into Standard Model particles. In this paper, we explore one possible exotic decay of the Vector-Like Quark with electric charge +5/3, X5/3. READ MORE
