  1. 11. Interplay between soft and hard processes in quantum chromodynamics

    Författare :Anders Edin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Strålningsvetenskap; Radiation biology; Strålningsbiologi; högenergifysik; High Energy Physics;

    Sammanfattning : In QCD, the theory of strong interactions, hard processes with large momentum transfers can be calculated using perturbation theory, while soft processes with small momentum transfers are poorly understood. In this thesis, phenomenological models of soft and hard QCD processes are developed and tested. LÄS MER

  3. 12. Multiparton Interaction Models and Parton Shower Studies

    Författare :Richard Corke; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiparton Interactions; Parton Showers; Phenomenological Models; QCD Phenomenology;

    Sammanfattning : This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. LÄS MER

  4. 13. Searches for the Charged Higgs at Hadron Colliders Based on the Tau Lepton Signature

    Författare :Yann Coadou; Tord Ekelöf; William Trischuk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : The Standard Model of particle physics has been very successful in predicting a wide range of phenomena and has so far been confirmed by all existing data to a very high precision.The work described in this thesis tests the limits of validity of the Standard Model (SM) in two areas believed to be sensitive to deviations from the theory: the observation of unpredicted particles and CP violation.
