1. 21. 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. 22. Skräck från bok till bild

   Kandidat-uppsats, Lunds universitet/Litteraturvetenskap

   Författare :Nicole Guldbrand; [2022]
   Nyckelord :Skräck; intermedial; adaptioner; adaption; Coraline; Neil Gaiman; Gaiman; Unheimliche; uncanny; horror; terror; barnlitteratur; barnbok; barnböcker; Fyhr; Freud; cosmic horror; cosmic; kosmisk; eldritch; Lovecraft; H.P Lovecraft; monster; andra världar; kusligt; kuslighet; obehagligt; obehag; Languages and Literatures;

   Sammanfattning : Denna kandidatuppsats undersöker hur skräck som motiv ter sig annorlunda när ett litterärt verk går från ett format till ett annat, via en komparativ granskning av Neil Gaimans barnbok Coraline (2002) och dess intermediala adaptioner. Granskningen görs utifrån ett narratologist perspektiv. LÄS MER

4. 23. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

   Master-uppsats, Stockholms universitet/Institutionen för astronomi

   Författare :Olof Nebrin; [2022]
   Nyckelord :Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

   Sammanfattning : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. LÄS MER

5. 24. Spin correlations in top quark pair production at the Large Hadron Collider

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

   Sammanfattning : 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. LÄS MER

7. 25. 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.
