  1. 1. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2022]
    Nyckelord :Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Sammanfattning : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. LÄS MER

  3. 2. 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. 3. Ghosts of Our Past: Neutrino Direction Reconstruction Using Deep Neural Networks

    Kandidat-uppsats, Uppsala universitet/Högenergifysik

    Författare :Sigfrid Stjärnholm; [2021]
    Nyckelord :neutrino; neural network; ICECUBE; AI; convolutional neural network; CNN; askaryan emission; charged current; neutral current; CC; NC; Keras; TensoFlow; neutrino; neuralt nätverk; ICECUBE; AI; askaryan emission; Keras; TensorFlow;

    Sammanfattning : Neutrinos are the perfect cosmic messengers when it comes to investigating the most violent and mysterious astronomical and cosmological events in the Universe. The interaction probability of neutrinos is small, and the flux of high-energy neutrinos decreases quickly with increasing energy. LÄS MER

  5. 4. Dark Matter – Direct Detection and Capture in the Sun

    Master-uppsats, KTH/Fysik

    Författare :Erika Lind; [2020]
    Nyckelord :Dark matter; direct detection; indirect detection; solar capture; inelastic dark matter; Mörk materia; direkt detektion; indirekt detektion; solinfångning; inelastisk mörk materia;

    Sammanfattning : Dark matter has been inferred from various observations such as in galaxy clusters, flat galactic rotation curves, gravitational lensing measurements and the cosmic microwave background. Despite overwhelming observational evidence and ongoing searches, a clear signal of dark matter has not yet been detected. LÄS MER

  7. 5. Kosmiska Neutriner

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

    Författare :Lara Mohatadi; Rasoul Lasek; [2020]
    Nyckelord :;

    Sammanfattning : Neutrinoobservationer kan ge mycket information om vad som händer ute i rymden. Den observationen och studien som ger den mest konkreta informationen är smaksammansättningar av neutriner som når jorden efter att den propagerat i rymden från dess källa. LÄS MER
