  1. 1. Potential for B-physics measurements with a fixed-target proton-collision experiment

    Detta är en avhandling från Department of Elementary Particle Physics, Lund University

    Författare :Jenny Ivarsson; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CP Violation; quantum field theory; Elementarpartikelfysik; HERA-B; Fixed Target; kvantfältteori; B Physics; Monte Carlo Simulations; Fysicumarkivet A:1999:Ivarsson;

    Sammanfattning : HERA-B is a high-energy physics experiment at HERA. It is a fixed-target experiment with a forward spectrometer to benefit from the strong boost of beauty hadrons. The main goal of HERA-B is to detect and measure the degree of CP violation in exclusive B-decays, with emphasis on the {em golden} decay, $golden$. LÄS MER

  2. 2. Multi-Strange and Charmed Antihyperon-Hyperon Physics for PANDA

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Thomé; Tord Johansson; Brian Quinn; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; antiproton; hyperon; strangeness; charm; polarisation; spin correlation; CP violation; Kärnfysik; Nuclear Physics;

    Sammanfattning : The prospects of studying multi-strange and charmed antihyperon-hyperon physics and CP violation in hyperon decays in the upcoming PANDA experiment at FAIR, Germany, have been studied in this thesis.The angular dependence on polarisation parameters in the decay of the spin 3/2 Omega hyperon was calculated using the density matrix formalism.

  3. 3. Electromagnetic and Spin Properties of Hyperons

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabetta Perotti; Stefan Leupold; Luis Alvarez Ruso; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electromagnetic form factors; hyperon physics; dispersion relations; QCD; chiral perturbation theory; CP violation; Fysik; Physics;

    Sammanfattning : The study of hyperons improves our understanding of nature in multiple ways. The intrinsic properties of hadrons are not fully understood at a fundamental level. Hence, the electromagnetic properties of hyperons provide complementary information to that of the nucleon and therefore allow for a broader investigation of the structure of matter. LÄS MER

  4. 4. Soft resummation and hard evolution : Renormalization group methods in effective theories and multi scalar models

    Detta är en avhandling från Department of Astronomy and Theoretical Physics, Lund University

    Författare :Joel Oredsson; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higgs; Particle physics; two-Higgs-doublet model; Soft-Collinear-Effective Theory; Renormalization;

    Sammanfattning : This thesis is composed out of five papers that deal with various problems intheoretical particle physics. While paper I is a precision calculation in aneffective theory of the Standard Model, paper II to V all deal with beyond theStandard Model physics. Paper IV is a manual for the tools developed during ourwork on paper II to V.Paper I. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Yann Coadou; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik 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.
