1. 11. Principal Component Analyses of Final States in Relativistic Nuclear Collisions using PYTHIA/Angantyr

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nicoline Krogh Hemme; [2020]
   Keywords : Relativistic Nuclear Collisions; Heavy-ion Collisions; Pythia; Angantyr; String Shoving; Colour Reconnection; Principal Component Analysis; Anisotropic Flow; Elliptic Flow; Event-by-event Fluctuations; Physics and Astronomy;

   Abstract : We develop a program to perform a principal component analysis of flow fluctuations using simulations of nuclear collisions produced by the PYTHIA/Angantyr event generator. We consider both p+p and p+Pb collision events and study the leading and subleading modes of the second flow harmonic. READ MORE

3. 12. Studies of Possible QGP Estimators in proton-proton Collisions

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Anna Önnerstad; [2019]
   Keywords : Physics and Astronomy;

   Abstract : This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator called Mid-Forward. READ MORE

4. 13. Xi Production in pp Collisions at Different Multiplicity and Spherocity

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Martin Angelsmark; [2019]
   Keywords : Particle Physics Quark Gluon Plasma ALICE LHC CERN Xi Baryon Transverse Spherocity Multiplicity; Physics and Astronomy;

   Abstract : The protons and neutrons that make up the atoms in our Universe are part of a larger group of particles called hadrons. Hadrons have an inner structure consisting of the elementary particles called quarks. The interaction of the quarks is described by the quantum field theory quantum chromodynamics. READ MORE

5. 14. Performance of jet subtraction in pPb and PbPb collisions, without collectivity

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Sebastian Grabowski; [2018]
   Keywords : heavy ion: scattering; Angantyr; underlying event; subtraction; jet: quenching; non-collectivity; stacking; jet: correlation; non-colliective; background; Physics and Astronomy;

   Abstract : We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8.

6. 15. Electrons from heavy- flavor semileptonic decays in proton-proton collisions at √s=13 TeV measured with the ALICE detector at the LHC

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Madeleine Petersson Sjögren; [2018]
   Keywords : LHC ALICE Heavy-ion physics particle physics heavy-flavor; Physics and Astronomy;

   Abstract : Heavy-flavor hadrons, containing charm and bottom quarks, serve as a tool available for the characterization of the hot and dense strongly interacting Quark Gluon Plasma state of matter, produced in heavy-ion collisions. As a benchmark for heavy-ion collision measurements, proton-proton collisions are also studied. READ MORE
