  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. 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

  3. 3. Implementation of Variational Autoencoder on the simulated particle collider data

    University essay from Uppsala universitet/Högenergifysik

    Author : Mário Alves Cardoso; [2021]
    Keywords : high energy physics; machine learning;

    Abstract : We study the possibility of applying deep learning algorithms, suchas Variational Autoencoders, on simulated particle collider data to detectBeyond the Standard Model events. In this report, we apply three dif-ferent processes of training the data for better eciency and the resultsof said training on detecting anomalies. READ MORE

  4. 4. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Ignacio Martínez Casasús; [2021]
    Keywords : Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Abstract : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). READ MORE

  5. 5. 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.
