  1. 1. Longser Antar Pulau: Indonesian cultural politics and the revitalisation of traditional theatre

    Författare :Jörgen Hellman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; etnografi; socialantropologi och etnologi: Java;

    Sammanfattning : The dissertation investigates the ambiguous role that cultural politics have played in the process of formulating an Indonesian national identity. Three case studies exemplify how cultural politics have been used by the state for the purpose of disciplining ethnic sentiments, at the same time as other groups have used the same discourse to express ideas contrary to the government controlled ideology.

    Sammanfattning : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. LÄS MER

  4. 3. Top quark and heavy vector boson associated production at the ATLAS experiment : Modelling, measurements and effective field theory

    Författare :Olga Bessidskaia Bylund; Jörgen Sjölin; Sten Hellman; Stéphanie Beauceron; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : The Standard Model (SM) of particle physics describes the elementary particles that constitute matter and their interactions. The predictions of the SM have been confirmed by numerous experimental results. LÄS MER

  5. 4. Studies of Top Physics Sensitivity and of Pile-Up Effects on Energy Reconstruction in the ATLAS Detector : A Licentiate Thesis About the Treatment of Troublesome $\tau$ and Producing Pulses to Probe Pile-up Problems

    Författare :Simon Molander; Sten Hellman; Jörgen Sjölin; Klas Hultqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tau; top quark; ATLAS; LHC; TILE calorimeter; sensitivity; cross-section; standard model; physics; optimal filtering; energy reconstruction; hadronic tau decay; fysik; Physics;

    Sammanfattning : This thesis presents two studies conducted using the ATLAS detectorat the Large Hadron Collider. The first one is a technical study abouthow out-of-time pile-up affects energy reconstruction using the optimalfiltering 2 algorithm in the TILE calorimeter sub detector. The studyis conducted using a pulse simulator software that is also described. LÄS MER
