1. 1. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

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

   Author : Jacob Lindahl; [2023]
   Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

   Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. 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. Can Feebly Interacting Massive Particles (FIMP) constitute Dark Matter?

   University essay from KTH/Fysik

   Author : Grandharva Appagere; [2021]
   Keywords : Dark Matter; Higgs¬portal; Freeze¬-in mechanism; FIMP; C-W Mechanism; Mörk materia; Higgsportal; frys-in-mekanism; FIMP; C-W mekanism;

   Abstract : In this study, we investigate the feasibility of Feebly Interacting Massive particles (FIMP) as possible candidates to constitute the observed Dark Matter abundance in the universe. FIMPs are particles that couple very feebly with known particles in the Standard Model (SM). READ MORE

5. 4. Signal background interference effects in lepton trident events with a new low mass mediator

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Patricia Andrea Gutiérrez García; [2020]
   Keywords : dark matter; pythia; matrix element corrections; LDM; Dire; Madgraph; dark photons; Physics and Astronomy;

   Abstract : In this project we present a phenomenological study of signal to background interference effects in leptonic tridents produced in parton showers. The interference effects are introduced by linking matrix element corrections of a kinetically mixed dark photon model to the parton shower Dire. READ MORE

6. 5. Probing the effect of dark matter velocity distributions on neutrino-based dark matter detection

   University essay from Uppsala universitet/Högenergifysik

   Author : Martin Ståhl; [2019]
   Keywords : Dark matter; WIMPs; velocity distribution; indirect detection;

   Abstract : Dark matter has a long history, but it was not until modern times that we have a chance of detecting it. This thesis focuses on the velocity distribution and its effect on indirect WIMP detection. Recently a new velocity distribution, based on data from SDSS and GAIA, was proposed. READ MORE
