  1. 1. A search for leptoquarks with the ATLAS detector and hardware tracking at the High-Luminosity LHC

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mikael Mårtensson; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Leptoquarks; Hough transform; LHC; ATLAS; HL-LHC; Particle physics; Particle tracking; Cluster finding; Trigger; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : This thesis presents a search for pair-production of scalar leptoquarks, decaying into third-generation particles, using proton-proton collisions delivered by the Large Hadron Collider (LHC) and recorded by the ATLAS detector. It also presents the development of a hardware track trigger for the Phase-II upgrade of the ATLAS experiment. LÄS MER

  3. 3. Identifying charged hadrons on the relativistic rise using the ALICE TPC at LHC

    Detta är en avhandling från Fysiska institutionen

    Författare :Philippe Gros; Lund University.; Lunds universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ILC; LHC; ALICE; TPC; Grid; pion spectra; Fysicumarkivet A:2011:Gros;

    Sammanfattning : The chain from hadron collisions to the physics results requires several important links. First the outcome of the collision is measured by the detectors. Then, the signal from the detector is processed and transformed into information relevant for the study of the physics processes. LÄS MER

  4. 4. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Edvin Sidebo; KTH.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; p p: scattering; ATLAS; LHC; charged particle: multiplicity; semiconductor detector: pixel; neural network: performance; track data analysis: cluster; charged particle: cluster; splitting; CERN LHC Coll; Physics; Fysik;

    Sammanfattning : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. LÄS MER

  5. 5. Measurements of Angular Correlations in Minimum Bias Events and Preparatory Studies for Charged Higgs Boson Searches at the Tevatron and the LHC

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Camille Bélanger-Champagne; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; D0; LHC; Tevatron; CERN; Fermilab; QCD; Monte Carlo tunes; Matrix Element method; Charged Higgs boson; Tau lepton; Trigger; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : Studies of minimum bias events at colliders probe the behavior of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters, which all need to be tuned to the observed data. LÄS MER
