  1. 1. Hadronic Decays of the ω Meson

    Författare :Lena Heijkenskjöld; Andrzej Kupsc; Tord Johansson; Michael Ostrick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hadronic decays; Light mesons; Meson-meson interactions; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : Two decay channels of the ω(782) meson, into π+π-π0 and π+π-, are studied. The dynamics of the three-pion channel is represented using a two-dimensional distribution, called a Dalitz plot. A high-statistics Dalitz plot distribution is needed to test theoretical predictions and increase understanding of the decay mechanism. LÄS MER

  4. 3. From Strange to Charm : Meson production in electron-positron collisions

    Författare :Joachim Pettersson; Karin Schönning; Andrzej Kupsc; Simon Eidelman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hadronic decays; Light mesons; Charmonium; Meson production; BESIII; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : Decays of pseudoscalar mesons into a lepton-antilepton pair are very rare within the Standard Model since they cannot proceed via a single photon process. The C-even neutral mesons can be produced in electron-positron collisions by a two-photon intermediate state. LÄS MER

  5. 4. Measurement of the Dalitz Plot Distribution for η→π+π−π0 with KLOE

    Författare :Li Caldeira Balkeståhl; Andrzej Kupsc; Tord Johansson; Simon Eidelman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Quark masses; Hadronic decays; Light mesons; Meson-meson interactions; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : The mechanism of the isospin violating η→π+π−π0 decay is studied in a high precision experiment using a Dalitz plot analysis. The process is sensitive to the difference between up and down quark masses. LÄS MER

  7. 5. Studies of the fragmentation process in hadronic decays of Z⁰ boson

    Författare :Oxana Smirnova; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fragmentation; gluon; QCD; hadron calorimeter; DELPHI; LEP; accelerator; particle; Fysik; Physics; Bose-Einstein correlations; Fysicumarkivet A:1996:Smirnova;

    Sammanfattning : This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. LÄS MER
