  1. 1. Luminosity determination and simulation of the LUCID detector at the ATLAS experiment

    Författare :Jacob Groth-Jensen; Partikel- och kärnfysik; ATLAS Collaboration; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; LUCID; Luminosity determination; Performance study; ATLAS; Gauge boson production; Fysicumarkivet A:2010:Groth-Jensen;

    Sammanfattning : The aim of this thesis is to describe how the luminosity can be measured in the ATLAS experiment at the Large Hadron Collider. Luminosity is a fundamental quantity that is used in most physics studies at the LHC. For example in order to measure cross sections. LÄS MER

  3. 2. Search for beyond Standard Model physics with same-sign dileptons

    Författare :Anthony Hawkins; Partikel- och kärnfysik; ATLAS Collaboration; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Doubly Charge Higgs; Beyond Standard Model; LHC; ATLAS; TRT; Same-sign leptons; Fysicumarkivet A:2014:Hawkins;

    Sammanfattning : An introduction into the theory and experimental background of particle physics and the ATLAS detector is given. The transition radiation tracker (TRT) which is vital to the particle tracking and identification is then described giving particular creedence to the calibration. The automation of this calibration is explained. LÄS MER

  4. 3. Silicon Tracking and a Search for Long-lived Particles

    Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Maurice Garcia-Sciveres; Joel Goldstein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; silicon; silicon tracking; radiation damage; neuromorphic; neuromorphic computing; long-lived particles; susy; rpvll; displaced vertices; pixel; pixel detector; fysik; Physics;

    Sammanfattning : The ATLAS Detector, below the surface of the Swiss-French border, measures the remnants of high-energy proton-proton collisions, accelerated by the Large Hadron Collider (LHC) at CERN. Recently the LHC paused operations, having delivered an integrated luminosity corresponding to 150 fb−1 of data at a centre-of-mass energy of 13 TeV. LÄS MER

  5. 4. Instrumentation for silicon tracking at the HL-LHC

    Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Thomas Schön; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; physics; particle physics; atlas; radiation damage; neuromorphic; kalman filter; fysik; Physics;

    Sammanfattning : In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. LÄS MER

  7. 5. Aspects of the ATLAS ITk Inner Tracker development for the high luminosity upgrade of the Large Hadron Collider

    Författare :Jonas Steentoft; Richard Brenner; Rebeca Gonzalez Suarez; Matti Kalliokoski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS ITk; Detector instrumentation; Applied physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The High Luminosity upgrade of the Large Hadron Collider (HL-LHC), necessitates that the ATLAS experiment replace their current Inner Detector (ID) system. The new Inner Tracker (ITk) will be an all silicon detector, utilising both pixel and strip sensors, with the aim of performing as well, or better than the current system - but in a much more challenging environment.
