  1. 11. Non-market goods derived from restoring flads, are they worth the trouble?

    University essay from Göteborgs universitet/Institutionen för marina vetenskaper

    Author : Jesper Hassellöv; [2022-06-23]
    Keywords : Flads; Ecosystem goods;

    Abstract : The quark archipelago is home to a unique environment called flad. These shallow lagoons are, trough an uplift up to 1cm year-1, changing appearance rather quickly and therefore create a niche environment. READ MORE

  3. 12. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Anton Wagner; [2022]
    Keywords : Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Abstract : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. READ MORE

  4. 13. Spin correlations in top quark pair production at the Large Hadron Collider

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Abstract : 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. READ MORE

  5. 14. Geometry studies of high energy 16O collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Aliaksei Kuzmenka; [2022]
    Keywords : Ion Collisions; Oxygen; Physics and Astronomy;

    Abstract : In this project a model of oxygen, 16O, nuclei, where the nucleons are organised in α-clusters, was implemented in the Pythia Monte Carlo event generator. To study the effects of the new model, some observables, such as the distribution of the number of the wounded nucleons, charged particle multiplicity in the forward and central pseudorapidity region, and the pseudorapidity distribution for different centrality bins and eccentricity, are compared to the model originally implemented in Pythia (Woods-Saxon).

  6. 15. Projections for charm balance functions in heavy-ion collisions

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

    Author : Tilde Bonnevier Wallstedt; [2022]
    Keywords : Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Abstract : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. READ MORE
