  1. 36. Exploring the Gauge Sector of a Composite Two-Higgs Doublet Model

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Adam Warnerbring; [2021]
    Keywords : two-Higgs doublet model; composite Higgs model; composite two-Higgs doublet model; Physics and Astronomy;

    Abstract : In this bachelor thesis we investigate the gauge sector of a specific composite two-Higgs doublet model, allowing more freedom for the gauge couplings and compositeness scales. From the underlying parameters we generate model realisations with the correct top mass, Higgs mass and electroweak vacuum expectation value, that satisfy theoretical constraints such as unitarity and perturbativity.

  3. 37. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

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

    Author : Axel Gallén; [2021]
    Keywords : LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

    Abstract : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. READ MORE

  4. 38. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Daniela Romero; [2021]
    Keywords : Higgs boson; vbf; vector boson fusion; high energy physics; lhc; proton collision; madgraph; simulation;

    Abstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE

  5. 39. Ω- Yields in pp Events at √s = 13 TeV Using the ALICE Detector

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

    Author : Henrik Pålsson; [2021]
    Keywords : LHC; ALICE; strangeness enhancement; charged multiplicity; Physics and Astronomy;

    Abstract : Ω- is a baryon which is rarely produced in proton collisions. The theoretical models for how these Ω- appear are yet not fully developed. Previous studies have shown that the experimental data did not agree with the models since more Ω- particles appeared in the proton collisions than expected. READ MORE

  6. 40. Coordinate conversion for the Hough transform

    University essay from Uppsala universitet/Högenergifysik

    Author : Edvin Eriksson; [2021]
    Keywords : particle accelerator; coordinate transformation; hough transform; uppsala; bachelor thesis; kandidatarbete; uppsala; fysik;

    Abstract : This thesis attempts to develop a conversion algorithm between local coordinates in constituent detector modules and global coordinates encompassing the whole detector structure in a generic detector. The thesis is a part of preparatory work for studying the Hough Transform as a means of track reconstruction in the level-1 hardware trigger in the upgraded trigger and data acquisition (TDAQ) system in the phase 2 upgrade of the ATLAS detector at CERN.
