  1. 21. 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. 22. Computational simulations of the Axion Longitudinal Plasma HAloscope

    University essay from Stockholms universitet/Fysikum

    Author : Tove Klaesson; [2022]
    Keywords : ;

    Abstract : The quantum chromodynamics axion is a very light hypothetical particle that may simultaneously solve the dark matter and the strong CP problem. Recently, a new type of haloscope that can detect the resonant conversion of axions to photons was suggested, The Axion Longitudinal Plasma HAloscope (ALPHA). READ MORE

  4. 23. Spin correlations in top quark pair production at the Large Hadron Collider

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Simon Ahlstedt; [2022]
    Keywords : Top quarks; Top quark pair production; LHC; Spin correlations; MadGraph5_aMC@NLO; Dilepton decay channel; Leading order; Interference effects; Event generation.; Physics and Astronomy;

    Abstract : In this work we investigate the spin correlation effect of the interference between signal and irreducible background events present in top quark pair production at the LHC at LO in the dilepton channel. To simulate the high energy proton-proton collisions of the LHC, MadGraph5_aMC@NLO framework is used as an event generator. READ MORE

  5. 24. 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.

  6. 25. HIGHLY CRITICAL GRAPHICS GENERATION ON A SYSTEM-ON-CHIP PLATFORM

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Fredrik Andersson; Rikard Karlsson; [2022]
    Keywords : ;

    Abstract : The critical applications domain stands today at the brink of a great divide. On one side, the deterministic and safe operational prerequisite of the system. On the other, an ever increasing demand for computational power and miniaturization. In some cases, the welfare of people hinge in the balance of these attributes. READ MORE
