  1. 6. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    University essay from Uppsala universitet/Högenergifysik

    Author : Rohini Sengupta; [2021]
    Keywords : Particle Physics; CERN; Future Circular Collider; FCC-ee; Heavy Neutral Leptons; Long-lived particles; Displaced signatures;

    Abstract : Heavy Neutral Leptons (HNLs) are the heavier counterparts of the light neutrinos of the Standard Model of particle physics. HNLs can simultaneously solve several of the problems the Standard Model cannot yet resolve, one example being that they provide a candidate for Dark Matter. READ MORE

  3. 7. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS

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

    Author : Alexander Ekman; [2019]
    Keywords : kaon; neutral kaon; K^0_L; K_Long; klong; single-particle response; response; detector response; calorimeter; ATLAS; CERN; jets; trigger level analysis; TLA; physics list; Monte Carlo; MC; Physics and Astronomy;

    Abstract : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. READ MORE

  4. 8. Xi Production in pp Collisions at Different Multiplicity and Spherocity

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

    Author : Martin Angelsmark; [2019]
    Keywords : Particle Physics Quark Gluon Plasma ALICE LHC CERN Xi Baryon Transverse Spherocity Multiplicity; Physics and Astronomy;

    Abstract : The protons and neutrons that make up the atoms in our Universe are part of a larger group of particles called hadrons. Hadrons have an inner structure consisting of the elementary particles called quarks. The interaction of the quarks is described by the quantum field theory quantum chromodynamics. READ MORE

  5. 9. Exotic Decays of a Vector-liketop Partner at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Alexander Skwarcan-Bidakowski; [2019]
    Keywords : Particle physics; Vector-like quarks; VLQ; Composite Higgs model; CHM; Top-partner; pseudo; Nambu-Goldstone boson; pNGB; NGB; ATLAS; LHC; CMS; Significance; Recast; CheckMate; CM; MadGraph; Pythia; Delphes; Detector; Analysis; Hierarchy Problem; Exotic; Decay; QFT; Quantum Field Theory; fermions; bosons; Jets; photons; leptons; 13 TeV; Missing Transverse Energy; momentum; hypothetical; selection criteria; Standard model; Signal; background; event; Higgs; Mechanism; Simulation; Confidence limit;

    Abstract : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).

  6. 10. Performance of jet subtraction in pPb and PbPb collisions, without collectivity

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Sebastian Grabowski; [2018]
    Keywords : heavy ion: scattering; Angantyr; underlying event; subtraction; jet: quenching; non-collectivity; stacking; jet: correlation; non-colliective; background; Physics and Astronomy;

    Abstract : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.
