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

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

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

    Sammanfattning : 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). LÄS MER

  3. 2. Neutrino Hotspots in the Universe: a Sensitivity Study Using the IceCube Neutrino Observatory

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kiana Ghiassi; Julia Salwén; [2023]
    Nyckelord :Astrophysics; Neutrino Astronomy; Particle Physics; Neutrinos; Blazars; Sensitivity Study; IceCube Neutrino Obesvatory;

    Sammanfattning : In this report, we aim to assess the sensitivity and 5$\sigma$ discovery potential of IceCube, the largest neutrino observatory on Earth, and compare it with prior findings. Our thesis will focus on a point source analysis, exploring the energy and declination dependencies, with particular emphasis on high-energy neutrinos. LÄS MER

  4. 3. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Anton Holmberg; [2022]
    Nyckelord :Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

    Sammanfattning : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

  5. 4. Study of the doubly charged Higgs boson single production using lepton parton distribution functions with the ATLAS detector

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

    Författare :Daniel Magdalinski; [2022]
    Nyckelord :doubly charged Higgs boson; ATLAS; lepton parton distribution function; same-sign; dilepton; beyond standard model; LHC; Physics and Astronomy;

    Sammanfattning : Searches for the doubly charged Higgs(H±±) aim to find evidence for models that could explain the origin of neutrino masses. Earlier searches at the LHC have used different production processes for the H±±, with the recent development of lepton parton distribution functions new leptonic production processes are able to be studied.

  7. 5. Studies of Dark Showers for Present and Future Colliders

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

    Författare :Nicoline Krogh Hemme; [2022]
    Nyckelord :high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Sammanfattning : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. LÄS MER
