  1. 11. Near detector simulation studies for CP violation discovery with ESSnuSB

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :In-Pyo Yeo; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The neutrino oscillation experiment ESSnuSB aims to measure the CP violation phase in the lepton sector with an intense neutrino beam produced at ESS. If the CP violation is discovered, then the matter-antimatter asymmetry of the Universe can be possibly explained. LÄS MER

  3. 12. Characterization of monopole induced air showers using CORSIKA

    Kandidat-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jan Rol; [2017]
    Nyckelord :monopole; cosmic ray; air shower;

    Sammanfattning : In this thesis a characterization of air showers induced by magnetic monopoles is presented. Monopoles are predicted to exist and be accelerated to relativistic velocities. High energy monopoles traversing earth’s atmosphere continuously deposit energy, inducing an air shower. LÄS MER

  4. 13. Improved Event-mixing for Resonance Measurements

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Mengke Cai; [2016]
    Nyckelord :Event mixing; Resonance; phi meson; Physics and Astronomy;

    Sammanfattning : This report first analyzed the reason for the deviation of the event-mixing method in background estimation for resonance research, and one possible explanation is that the event-mixing method can not reproduce the specific angular distribution of produced particles caused by jet-effects. This assumption was checked by Monte-Carlo simulations with PYTHIA, and a certain method of correction called reweighing was proposed to improve the event-mixing method. LÄS MER

  5. 14. Developing a test procedure for neutron detection/non detection using a Small TPC Prototype

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Nicholai Mauritzsson; [2016]
    Nyckelord :Time Projection Chamber; TPC; neutron; anti-neutron; Gas Electron Multiplier; ALTRO; Readout electronics; Physics and Astronomy;

    Sammanfattning : This work relates to the proposed n-nbar experiment at ESS and covers a procedure with which future neutron research can be made using a small TPC prototype. Settings for the GEM amplification voltage supply and main drift field across the chamber have been established using minimum ionizing cosmic muons as a reference. LÄS MER

  7. 15. Majorana Neutrinos - Same Sign Di-Muon Investigations in 8 TeV Datasets with the BUMPHUNTER Algorithm

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Einar Elén; [2016]
    Nyckelord :BUMPHUNTER; Majorana Neutrino; ATLAS; Di-muon; Neutrino; Physics and Astronomy;

    Sammanfattning : A hypertest-algorithm, the BUMPHUNTER, is introduced briefly and tested by probing events containing muons in 8 TeV datasets from the ATLAS detector at the Large Hadron Collider (LHC) at CERN against a background spectrum created by selecting muons from different collisions. The hypertest looked for excesses of same sign di-muon pairs which could indicate the existence of a Majorana neutrino. LÄS MER
