1. 1. Event Geometry and Anisotropic Flow in Proton-Proton Collisions

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

   Författare :Johannes Holst; [2021]
   Nyckelord :high energy physics; particle physics; proton; collision; quark-gluon plasma; flow; anisotropy; anisotropic flow; elliptic flow; initial state; geometry; eccentricity; gaussian; cms; alice; lhc; Physics and Astronomy;

   Sammanfattning : We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. LÄS MER

3. 2. Investigation of Impact Parameter Profiles in Multi-Parton Interactions

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

   Författare :Martin Korsfeldt; [2020]
   Nyckelord :Angantyr; Impact Parameter; Multiparton Interaction; Physics and Astronomy;

   Sammanfattning : The purpose of this thesis was to implement an alternative method to calculate the overlap function, which describe to what extent two protons overlap with each other spatially, into PYTHIA8 in order to determine how it affected the average number of multiparton interactions. The new overlap function is based on an explicit impact parameter picture, whereas PYTHIA8s overlap function uses an implicit impact parameter picture. LÄS MER
