  1. 21. Radiative Corrections Beyond the Soft-Photon Approximation

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Jacob Lindahl; [2021]
    Keywords : Soft-Photon Approximation; Bremsstrahlung Correction; Transition Form Factor; Radiative Corrections; Physics and Astronomy;

    Abstract : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. READ MORE

  2. 22. Exploring the Gauge Sector of a Composite Two-Higgs Doublet Model

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Adam Warnerbring; [2021]
    Keywords : two-Higgs doublet model; composite Higgs model; composite two-Higgs doublet model; Physics and Astronomy;

    Abstract : In this bachelor thesis we investigate the gauge sector of a specific composite two-Higgs doublet model, allowing more freedom for the gauge couplings and compositeness scales. From the underlying parameters we generate model realisations with the correct top mass, Higgs mass and electroweak vacuum expectation value, that satisfy theoretical constraints such as unitarity and perturbativity.

  3. 23. Characterisation of Models of New Physics at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakub Salko; [2020]
    Keywords : ;

    Abstract : The goal of this thesis is the development and application of model-independent analysis techniques to characterise New Physics states of different kinds from their signatures at the LHC and future colliders. In the first part of the thesis, we outline the general steps from the building of the simplified model and identification of the parameter space to the characterisation potential of the current searches with the focus on the characterisation between different scenarios of Beyond the Standard Model physics.

  4. 24. Searching for Dark Photons with Jet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ashar Ahmed Kamal; [2020]
    Keywords : light dark matter; jet substructure; Physics and Astronomy;

    Abstract : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. READ MORE

  5. 25. Dark Photon decay generated by muons in the SHiP experiment

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Elizaveta Yakovleva; [2020]
    Keywords : dark matter; particle physics; particle accelerators; new physics;

    Abstract : This project has investigated the muon background of the SHiP experiment to determine whether it can boost the experiment sensitivity to visible Dark Photon decay. Using Fermi-Weizsäcker-Williams approximation to muon scattering we found the probability of muons generating massive photons, using Bremsstrahlung and direct lepton pair production as an estimation of the frequency of muon EM-interactions.
