1. 1. Validation of simulation with enhanced kaon production to investigate kaon background for LDMX

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

   Författare :Lisa Andersson Loman; [2023]
   Nyckelord :Dark matter; experimental physics; simulations; kaons; particle physics; LDMX; background studies; mörk materia; partikelfysik; kaoner; Physics and Astronomy;

   Sammanfattning : Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. LÄS MER

3. 2. 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.

4. 3. Signal and Background Studies at 8 GeV for the Light Dark Matter eXperiment

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

   Författare :Péter György; [2020]
   Nyckelord :LDMX; Dark Matter; Light Dark Matter; 8 GeV; Physics and Astronomy;

   Sammanfattning : Light dark matter is a hypothesized form of dark matter in the 1 MeV to 1 GeV mass range. The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of light dark matter, by colliding an electron beam with a tungsten target and assembling a set of events that potentially indicate the existence of light dark matter.

5. 4. J/psi suppression via string interactions in Au-Au collisions at 200 GeV/NN

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

   Författare :Julian Boy; [2020]
   Nyckelord :Suppression; gold-gold collisions; string interactions; fluxtubes nuclear modification factor; Physics and Astronomy;

   Sammanfattning : In 2018 the Relativistic Heavy Ion Collider (RHIC) reported sig- nals of a strongly coupled quark gluon plasma. This plasma is thought to be the reason for J/psi suppression when a fraction of the produced J/psi's dissolves due to the high-energy density of quarks and gluons. LÄS MER

7. 5. Analysis of the Hard Spectrum BL Lac Source 1H 1914-194 with Fermi-LAT Data and Multiwavelength Modelling

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Dominic Gächter Sundbäck; [2018]
   Nyckelord :;

   Sammanfattning : The very-high-energy gamma-ray emission of the hard spectrum BL Lac source 1H1914-194 has been studied with Fermi-LAT data covering a nearly ten-year period between August 2008 until March 2018 in the energy range of 300 MeV to 870 GeV. The mean flux has been determined as 8.4 x 10-9±3.5 x 10-10 photon cm-2 s-1. LÄS MER
