  1. 1. Dark Matter signals at the Large Hadron Collider with Deep Learning

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Max Andersson; Edward Glöckner; Carl Löfkvist; [2023]
    Nyckelord :Machine Learning; Dark Matter; Classification; Regression; Particle Physics; Supersymmetry; LHC; CERN;

    Sammanfattning : While holding a firm position in popular culture and science fiction, Dark Matter (DM) is nonetheless a highly relevant topic at the forefront of modern particle physics. We study the applicability of characterizing DM particle candidates SUSY neutralino and sneutrino using Deep Learning (DL) methods. LÄS MER

  3. 2. Simplified likelihoods for stop searches with one lepton in ATLAS

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Karl Lundkvist; [2022]
    Nyckelord :supersymmetry; particle; physics; stop; squark; neutralino; MSSM; pMSSM;

    Sammanfattning : .... LÄS MER

  4. 3. Simulation of Dark Matter Using micrOMEGAs

    Kandidat-uppsats, KTH/Teoretisk fysik

    Författare :Nikolaos Kalkitsas; Thom Jäderlund; [2015]
    Nyckelord :;

    Sammanfattning : Weakly interactive massive particles (WIMPs) are one of the most popular dark matter candidates and in our study we have decided on a WIMP based model due to its accurate predictions of the dark matter (DM) relic density. To determine a possible WIMP, we have used the minimal supersymmetric model (MSSM), an extension of superymmetry (SUSY). LÄS MER

  5. 4. Faster Dark Matter Calculations Using the GPU

    Kandidat-uppsats, Fysikum

    Författare :Sebastian Liem; [2011]
    Nyckelord :dark matter; DarkSUSY; GPU; GPU calculations; CUDA;

    Sammanfattning : We have investigated the use of the graphical processing unit to accelerate the software package DarkSUSY. DarkSUSY is, among other things, used for calculating the dark matter relic density -- an measurable quantity -- given the supersymmetric neutralino, χ, as a dark matter candidate. LÄS MER

  7. 5. Associated charged Higgs boson and squark production in the NUHM model

    Uppsats för yrkesexamina på avancerad nivå, Högenergifysik

    Författare :Gustav Lund; [2010]
    Nyckelord :Charged Higgs boson; NUHM; squark; supersymmetry;

    Sammanfattning : Conventional searches for the charged Higgs boson using its production in association with Standard Model (SM) quarks is notoriously weak in the mid-tanB range. Hoping to find an alternate channel to fill this gap, the production of the charged Higgs boson in association with supersymmetric squarks is studied. LÄS MER
