  1. 21. Spin correlations in top quark pair production at the Large Hadron Collider

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Simon Ahlstedt; [2022]
    Nyckelord :Top quarks; Top quark pair production; LHC; Spin correlations; MadGraph5_aMC@NLO; Dilepton decay channel; Leading order; Interference effects; Event generation.; Physics and Astronomy;

    Sammanfattning : In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. LÄS MER

  3. 22. Complementarity of high energy and high intensity experiments for dark photon benchmarks

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Joshua Greaves; [2022]
    Nyckelord :Dark matter; LDMX; Dark photon; Complementarity; Snowmass; Relic density; Thermal relic; Relic abundance; Cross section; Constraints; Limits; Minimal models; Energy frontier; Intensity frontier; Madgraph; Madanalysis; Vector mediated; Physics and Astronomy;

    Sammanfattning : Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others.

  4. 23. The Dark Side of Mineral Sourcing : The Responsible Sourcing Practices of Industrial Manufacturing Firms

    Master-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Ajnur Mujanovic; Erik Österberg; [2022]
    Nyckelord :Responsible sourcing; supply chain due diligence; supply chain visibility; traceability; supply chain management; Digital Twin; Etiskt inköp; supply chain due diligence; supply chain visibility; spårbarhet; supply chain management; Digital Twin;

    Sammanfattning : In order to succeed with the Sustainable Development Goals, the mining of minerals will need to not only continue, but increase in the coming years. The extraction of minerals such as gold and cobalt is often associated with human rights violations and the financing of criminal enterprises. LÄS MER

  5. 24. Planes of satellite galaxies

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Jessica Laura Erika Kocher; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. LÄS MER

  7. 25. Baksidan av djurskyddsarbetet : finns det ett samband mellan veterinärernas djurskyddsanmälningar och hot, trakasserier och våld mot veterinärer i Sverige?

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Environment and Health

    Författare :Mikaela Neijdebro; [2022]
    Nyckelord :djurskydd; kliniskt verksamma veterinärer; anmälningsplikt;

    Sammanfattning : En viktig del av veterinärers roll i samhället är upprätthållandet av svenskt djurskydd. Ett av veterinärens verktyg är djurskyddsanmälningar, och veterinärer har en lagstadgad plikt att anmäla misstanke om brott mot djurskyddslagstiftningen till länsstyrelsen. LÄS MER
