  3. 2. MSSM Higgs to τ τ and Optimizing Sensitivity : Report for Advanced Physics - Project Course 1FA565

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :August Wollter; [2018]
    Nyckelord :;

    Sammanfattning : I replicated the H/A → τ μ τ had analysis of the MSSM extension to the stan-dard model with the ATLAS experiment. I investigated, using a transformedBDT score for τ -lepton identification with a flat distribution, with more work-ing points than the standard loose, medium and tight, the sensitivity of theanalysis.

  4. 3. Searching for the charged Higgs boson in the tau nu analysis using Boosted Decision Trees

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jesper Hallberg; [2016]
    Nyckelord :Higgs; charged higgs; atlas; machine learning; ML; BDT; boosted decision trees; LHC; BSM; BSM physics; standard model; MSSM;

    Sammanfattning : his thesis implements a multivariate analysis in the current cut- based search for the charged Higgs bosons, which are new scalar particles predicted by several extensions to the Standard Model. Heavy charged Higgs bosons (mH± mtop) produced in association with a top quark de- caying via H± → τν are considered. LÄS MER

  5. 4. 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

  7. 5. Studies of charged Higgs bosons at the Compact Linear Collider

    Master-uppsats, Högenergifysik

    Författare :Johan Relefors; [2011]
    Nyckelord :;

    Sammanfattning : The Compact Linear Collider is an electron-positron collider being developed by CERN and collaborating universities. With a center of mass energy of 3 TeV it will be used to further explore TeV scale physics after the Large Hadron Collider. LÄS MER
