  1. 1. Improved Event-mixing for Resonance Measurements

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

    Author : Mengke Cai; [2016]
    Keywords : Event mixing; Resonance; phi meson; Physics and Astronomy;

    Abstract : 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. READ MORE

  3. 2. Can e+e- → ηπ+π- be detected at DAΦNE?

    University essay from Uppsala universitet/Kärnfysik

    Author : Viktor Thorén; [2015]
    Keywords : simulation; eta; pi ; pi-; e e- collisions;

    Abstract : Studying the annihilation of e+e- into hadrons is of great interest in the search for physics beyond the standard model. The cross sections of specific hadronic channels can be used in precise test of the Standard Model, or to estimate the anomalous muon magnetic moment, for which there are discrepancies between theory and experiment.

  4. 3. Vector Meson Masses in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Douglas Svensson Seth; [2013]
    Keywords : Theoretical particle physics; anti-de Sitter space; quantum chromodynamics; meson masses; Witten diagrams.; Physics and Astronomy;

    Abstract : We study the anti-de Sitter/conformal field theory correspondence (AdS/CFT correspondence) and investigate in a scalar model how n point functions can be calculated through functional derivatives and how they can be obtained with the use of Witten diagrams instead. We also study a previous anti-de Sitter/quantum chromodynamics (AdS/QCD) model where the mass of the phi meson has not been considered. READ MORE
