26. Constraining the Higgs width in Higgs production associated with a top quark pair
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

27. Samverkande system för saffranslökshantering för inomhusproduktion i Sverige
Kandidat-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utvecklingSammanfattning : Currently, all commercial cultivation of saffron takes place in outdoor fields, and the work is largely carried out manually. The company BlueRedGold is a Swedish startup that aims to revolutionize commercial saffron cultivation by developing a method to grow saffron indoors year-round using fully automated processes.

28. Asymptotic Symmetries and Dressed States in QED and QCD
Master-uppsats, Stockholms universitet/FysikumSammanfattning : Infrared divergences arising in theories with massless gauge bosons have been shown to cancel in scattering amplitudes when using dressed states constructed from the Faddeev- Kulish approach to the asymptotic states. It has been established that these states are closely related to asymptotic symmetries of the theory, that is, non-vanishing gauge trans- formations at the asymptotic boundary. LÄS MER
29. The Impact of Swampland Conjectures
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : The Swampland program is way of sorting effective field theories based on conjectures of how an effective field theory consistent with quantum gravity should look like. In this thesis we take a closer look at the No Global Symmetries Conjecture, the Weak Gravity Conjecture, the de Sitter Conjecture and the Trans-Planckian Censorship Conjecture. LÄS MER
30. Gravity water waves over constant vorticity flows: from laminar flows to touching waves
Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/MatematikcentrumSammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER
