1. 6. The impact of initial state radiation on jets from PbPb collisions

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Hilmi Kycyku; [2021]
   Nyckelord :heavy-ion physics; QGP; quark-gluon plasma; kvark-gluon plasma; initial state radiation; jets; medium response; Physics and Astronomy;

   Sammanfattning : This thesis presents the study of how initial state radiation impacts jets produced in pp and PbPb collisions, by investigating the transverse momentum spectra, the rapidity spectra and the differential jet shape. This is done for central collisions with nucleon-nucleom COM energy 2.76 TeV and 5.02 TeV. LÄS MER

3. 7. Evaluation of float-truncation based compression techniques for the ATLAS jet trigger

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Love Kildetoft; [2021]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Data compression methods allow more data to be stored within a certain storage framework while still keeping the characteristics of the data in question. At the Large Hadron Collider on the grounds of CERN in Switzerland, limited data storage capability is and has always been an urgent problem. LÄS MER

4. 8. Searching for Dark Photons with Jet

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Ashar Ahmed Kamal; [2020]
   Nyckelord :light dark matter; jet substructure; Physics and Astronomy;

   Sammanfattning : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. LÄS MER

5. 9. Investigating RT using two-particle angular correlations in proton-proton collisions

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Dilan Chroscik; [2020]
   Nyckelord :particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

   Sammanfattning : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. LÄS MER

7. 10. Deep Autoencoders for Compression in High Energy Physics

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Eric Wulff; [2020]
   Nyckelord :ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; high energy physics; data compression; Physics and Astronomy;

   Sammanfattning : Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. LÄS MER
