  1. 11. What Is the Impact of World Expositions on the Trade Volume in Exports?

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Albin Nilsson; Leonard Xander; [2023]
    Keywords : Trade; Exports; Mega-events; World Expositions;

    Abstract : Using the Structural Gravity model, this thesis analyzes the impact of post-war world expositions and specialized expositions on the trade volume in exports. The study runs LSDV regressions on three types of panel data for 183 countries between 1950 to 2017, with a total of 792,720 observations. READ MORE

  3. 12. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : José Guilherme Rodrigues de Albuquerque Vale; [2023]
    Keywords : Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

    Abstract : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). READ MORE

  4. 13. European Union and Trade Flows: The Case of Lithuania

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Eva Businskyte; [2023]
    Keywords : trade; European Union; Lithuania; gravity model; Business and Economics;

    Abstract : This paper examines the impact of EU integration on Lithuania's direction of trade flows. Using a gravity model and bilateral trade data from 1995 to 2020, the study aims to understand changes in trade flows after joining the EU and provide practical implications for policymakers, businesses, and investors.

  5. 14. Constraining the Higgs width in Higgs production associated with a top quark pair

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

    Author : Benjamin Dahlén; [2023]
    Keywords : Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Abstract : 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.

  6. 15. The Impact of Swampland Conjectures

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Daniel Nilsson; [2023]
    Keywords : String theory; Quantum gravity; Swampland program; Effective field theories;

    Abstract : 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. READ MORE
