  2. 1. Theoretical Studies of Hadronic Reactions with Vector Mesons

    Author : Carla Terschlüsen; Stefan Leupold; Stefan Scherer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Vector mesons; Effective field theories; Chiral Lagrangian; Meson-meson interactionss; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : Aiming at a systematic inclusion of pseudoscalar and vector mesons as active degrees of freedom in an effective Lagrangian, studies have been performed in this thesis concerning the foundations of such an effective Lagrangian as well as tree-level and beyond-tree-level calculations. Hereby, vector mesons are described by antisymmetric tensor fields. READ MORE

  4. 2. Soft and Hard Mesons in Chiral Perturbation Theory

    Author : Ilaria Jemos; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. READ MORE

  5. 3. A study of mu-mu- and e-mu-pairs produced in 450 GeV/c p-Be--collisions in HELIOS, and software development for DELPHI

    Author : Sverker Johansson; Jönköping University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik;

    Abstract : The main part of this thesis treats measurements in the HELIOS experiment of the production of e-mu and mu+mu-pairs in 450 GeV/c p-Be collisions. The mumu measurement covers the kinematical covers the kinematical range of 2Mmu < M < 1.5 GeV, 0.03 < xF < 0. READ MORE
