  1. 1. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Olsson; [2022]
    Keywords : Dark matter; particle phenomenology; LHC; MadGraph; standard model; beyond standard model;

    Abstract : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. 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. Extending the Standard Model by a Dark and Visible Scalar Singlet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Aram Fatah; [2020]
    Keywords : The two real singlet model; higgs boson; dark matter; beyond the standard model; bsm; scalar; Physics and Astronomy;

    Abstract : In this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. READ MORE

  5. 4. Study of Dark Matter Models in Astrophysics and Particle Physics

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

    Author : Isabelle John; [2019]
    Keywords : Physics and Astronomy;

    Abstract : From astrophysical and cosmological observations, it is known that most of the matter in the Universe is dark. This matter could be explainable by new particles, not included in the Standard Model of Particle Physics. READ MORE

  6. 5. Cosmological probes of the early universe with Axions & Gravitational Waves

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Nicklas Ramberg; [2019]
    Keywords : axions; early universe; dark matter; gravitational waves; modified cosmology; cosmic strings; axion; tidigt universum; mörk materia; gravitationsvågor; modifierad kosmologi; kosmiska strängar;

    Abstract : This thesis uses theoretical studies, and numerical simulations to provide results of the experimental reach to detect the QCD axion as dark matter in a Non-standard cosmological background. Assuming that the QCD axion constitutes the full CDM abundance of the universe, this thesis elaborates on its potential detection from experimental setups for the mass window of the axion. READ MORE
