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

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2022]
    Keywords : Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Abstract : 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. READ MORE

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

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

    Author : Joshua Greaves; [2022]
    Keywords : 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;

    Abstract : 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

    University essay from Uppsala universitet/Högenergifysik

    Author : Sigfrid Stjärnholm; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from KTH/Fysik

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

    Abstract : 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. READ MORE

  6. 5. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Carl-Fabian Strid; [2019]
    Keywords : particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

    Abstract : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. READ MORE
