  1. 1. Search for Higgs-like bosons through optimization of top-quark modelling

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Rafael Antonio Lopez; [2021]
    Keywords : ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

    Abstract : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. READ MORE

  2. 2. The Changing Character of Mars’ Bow Shock

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Östman; [2021]
    Keywords : Bow shock; Space plasma physics; Mars;

    Abstract : The aim of the project is to investigate the characteristics and causes of two different types of bow shocks at Mars. We define Type 1 as an undefined, drawn out ramp, and Type 2 as a shorter duration ramp that has clearer characteristics and behaves more like a step increase in the magnetic field. READ MORE

  3. 3. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Johan Leygonie; [2021]
    Keywords : QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

    Abstract : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. READ MORE

  4. 4. Calibration of a Fast Neutron Time-of-Flight System

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Armando Javier Morales Urrutia; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Future experiments with thermal neutrons at neutron facilities may encounter fast neutrons as sources of background. Understanding fast neutron behavior on an event-by-event basis in a detector is important for these complementary thermal neutron experiments. One way to study fast neutron events is by performing a time-of-flight measurement. READ MORE

  5. 5. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Rebecca Jigström Madeira; [2021]
    Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

    Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE
