1. 6. Long-Lived Particles from exotic Higgs decays at the FCC-ee

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Magdalena Vande Voorde; [2023]
   Nyckelord :;

   Sammanfattning : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

3. 7. Space Heat Power Demand for Existing Buildings : Feasibility, Improvement-Measures, and Impact on Climate Performance Using a Swedish Multi-Dwelling Building as Case Study

   Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Andreas Holmén; [2022]
   Nyckelord :;

   Sammanfattning : The most commonly used indicators of energy performance of existing buildings in Sweden, Specific Energy Use (SEU) and Primary Energy Use (PEU), are very rough measures that does not account for short term effects and therefore they are not necessarily well suited to evaluate climate performance of existing buildings. In this thesis the similar but slightly different indicators Miljöbyggnad Heat Power Demand (MHPD) (Värmeeffektbehov in Swedish) and Feby Heat Loss Number (FHLN) (Värmeförlusttal in Swedish), both indicators of Space Heat Power Demand (SHPD), has been evaluated as complementary indicators to SEU and PEU.

4. 8. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Xingtong Wu; [2022]
   Nyckelord :;

   Sammanfattning : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. LÄS MER

5. 9. Rejection of the Photon Induced Background in LDMX at 8 GeV

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

   Författare :Erik Wallin; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The Light Dark Matter eXperiment (LDMX) is a proposed fixed target experiment at SLAC's LCLS-II electron beamline that will attempt direct production of sub-GeV dark matter, measurable through a missing momentum and missing energy signature. An initial run of LDMX is planned at 4 GeV beam energy, for which a study on LDMX's capabilities to separate dark matter production events from the standard model background was previously performed.

7. 10. Investigation of Autoencoders for Jet Images in Particle Physics

   Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Partikel- och kärnfysik

   Författare :Jessica Lastow; [2021]
   Nyckelord :data compression; anomaly detection; jet image; autoencoder; dark matter; machine learning; ATLAS; hadron jet; particle physics; high energy physics; Physics and Astronomy;

   Sammanfattning : Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles.
