  1. 1. Reconstruction of spin observables in the pbar p → anti-Ω Ω reaction

    University essay from Uppsala universitet/Kärnfysik

    Author : Arnela Hrbat; [2023]
    Keywords : ;

    Abstract : The aim of this project was to reconstruct the spin observables of hyperons in the bar p → anti-ΩΩ reaction using a novel formalism that was developed at Uppsala University, using the standard event generator EvtGen. EvtGen is the event generator that is used in PandaRoot, but in this work, it is used as the standalone software. READ MORE

  3. 2. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Íñigo de Loyola Chacartegui Rojo; [2023]
    Keywords : Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

    Abstract : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

  4. 3. 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

  5. 4. Development of an event generator for antihyperon-hyperon pair production in antiproton-proton collisions

    University essay from Uppsala universitet/Kärnfysik

    Author : Vitor Jose Shen; [2022]
    Keywords : MC event generator; Antihyperon-hyperon pair; Antiproton-proton collisions; PANDA; ROOT; 4-vector kinematics; Angular distribution;

    Abstract : The goal of this project was to develop a lightweight Monte-Carlo (MC) event generator for hyperon pair production in antiproton-proton collisions, and demonstrate it in one of the hyperon decay reaction channels, which is collisions of proton and antiproton to lambda hyperon and anti-lambda hyperon, and they decay to antiproton-positive pion pair, and proton-negative pion pair. The prototype of this external MC event generator we presented here is based on the software framework of ROOT. READ MORE

  6. 5. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE
