  1. 1. The Higgs Width in Higgs production in association with a W+ boson

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Wijeratne Mohandiramge Umashi Navisha Fernando; [2023]
    Keywords : Higgs boson; Higgs width; off-shell; on-shell; narrow-width approximation; MadGraph5_MC@NLO; W boson; supersymmetry; dark matter; Physics and Astronomy;

    Abstract : The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. READ MORE

  3. 2. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

    University essay from Uppsala universitet/Kärnfysik

    Author : Benjamin Verbeek; [2023]
    Keywords : hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

    Abstract : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. READ MORE

  4. 3. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  5. 4. The kaon electromagnetic mass difference in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Jack Borthwick; [2016]
    Keywords : particle physics; AdS QCD; AdS CFT; kaon; electromagnetic mass difference; quantum field theory; Physics and Astronomy;

    Abstract : In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. READ MORE
