11. Strange Hadron Production as a Function of Multiplicity and Transverse Spherocity in proton-proton Collisions at $\sqrt{s}=13$~TeV
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis presents the study of the K$^{0}_{s}$, $\Lambda$, and $\bar{\Lambda}$ production in pp collisions at $\sqrt{s}=13$~TeV recorded by the ALICE experiment at the LHC. The K$^{0}_{s}$, $\Lambda$, and $\bar{\Lambda}$ particles are reconstructed in the transverse momentum ($p_{\mathrm{T}}$) range of $1.0-12. READ MORE

12. Studying the sensitivity of the ATLAS mono(H-bb) + missing transverse momentum search for a Dark Higgs signal
University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenAbstract : Dark Matter is one of the biggest mysteries in physics of our time, with an overwhelming amount of evidence for its existence but lack of direct observation (at time of writing). The focus of this thesis is to reimplement an ATLAS analysis used for Dark Matter searches in the mono-H(bb) channel, and use that analysis in order to study the signal of a new particle called Dark Higgs.

13. The space--time structure of hadron production in high-energy collisions
University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : In this thesis, the space--time picture of the hadronization model has been implemented in the event generator Pythia. From this implementation, the hadronic behaviour has been studied for different scenarios, in order to begin addressing the unexpected collective behaviour of high-multiplicity pp events, which is typical for heavy-ion collisions.

14. Feasibility of new Dark Matter search at ATLAS
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : This thesis examines the idea of calibrating Level 1 jets. These are used in the Trigger-Level Analysis at the ATLAS in the search for a new mediator, in this case between Standard Model and Dark Matter particles. In the thesis, the idea to calibrate the Level 1 jets is investigated. READ MORE

15. Parton Shower Algorithms - Possible Improvements
University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : In this Master thesis, two directions have been explored to improve the current parton shower algorithm of the event generator Pythia. Firstly, three choices of transverse-momentum-ordered evolution variable have been studied for final-state radiation in order to allow more flexibility within the algorithm. READ MORE
