  1. 1. 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

  2. 2. Investigation of Autoencoders for Jet Images in Particle Physics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Partikelfysik

    Author : Jessica Lastow; [2021]
    Keywords : data compression; anomaly detection; jet image; autoencoder; dark matter; machine learning; ATLAS; hadron jet; particle physics; high energy physics; Physics and Astronomy;

    Abstract : Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles.

  3. 3. Quartic Higgs self-coupling at a 100 TeV pp collider

    University essay from Lunds universitet/Teoretisk partikelfysik

    Author : Sebastian Grabowski; [2021]
    Keywords : Quartic Higgs self-coupling; Triple Higgs production; Future Circular Collider; FCC; MadGraph; MadAnalysis; Events selection; selection strategy; Physics and Astronomy;

    Abstract : We present a parton-level phenomenological study of triple-Higgs production at leading order in proton-proton collisions at a center-of-mass energy of 100 TeV with an integrated luminosity of 30 ab^-1. This study aims to estimate the prospects for measuring the signal hhh production observable at the Future Circular Collider. READ MORE

  4. 4. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Daniela Romero; [2021]
    Keywords : Higgs boson; vbf; vector boson fusion; high energy physics; lhc; proton collision; madgraph; simulation;

    Abstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE

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

    University essay from Lunds universitet/Partikelfysik; 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
