  1. 11. ATLAS Inner Tracker Upgrade for HL-LHC: Silicon microstrip detector metrology

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

    Author : Xiangyu Xu; [2023]
    Keywords : High energy physics experiment; LHC; HL-LHC; ATLAS; ITk; Metrology; Measurement; Physics and Astronomy;

    Abstract : The Large Hadron Collider (LHC) will be upgraded to the High-Luminosity LHC (HL-LHC) by the end of this decade, with five times larger luminosity and 200 inelastic collisions per proton-proton bunch crossing. Thus, the ATLAS detector is challenged to survive the stronger radiation and the increased particle flux. READ MORE

  3. 12. Forward-Backward Multiplicity Correlations for Proton-Proton Collisions with ALICE at LHC-CERN

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

    Author : August Koppers; [2022]
    Keywords : ALICE; Particle physics; CERN; LHC; QCD; pp collisions; Lund string model; Two particle correlation; Physics and Astronomy;

    Abstract : This thesis presents the study of two-particle pseudorapidity correlations in pp-collisions at √s = 13 TeV using the ALICE detector at LHC, CERN. The correlation function was calculated as a function of multiplicity and was repeated for several multiplicity classes and different charge combinations in the forward-backward and central regions of the detector, respectively.

  4. 13. 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

  5. 14. 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

  6. 15. 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.
