1. Quartic Higgs self-coupling at a 100 TeV pp collider
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We present a parton-level phenomenological study of triple-Higgs production at leading order in proton-proton collisions at a center-of-mass energy of 100 TeV with an integrated luminosity of 30 ab^-1. This study aims to estimate the prospects for measuring the signal hhh production observable at the Future Circular Collider. READ MORE

2. Signal background interference effects in lepton trident events with a new low mass mediator
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : In this project we present a phenomenological study of signal to background interference effects in leptonic tridents produced in parton showers. The interference effects are introduced by linking matrix element corrections of a kinetically mixed dark photon model to the parton shower Dire. READ MORE

3. PARTON SHOWER UNCERTAINTIES ON THE TOP MASS
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : The non-Abelian QCD nature allows for pp collisions to contain gluon emissions off quarks as well as gluon branchings into further gluons — a structure that can be described by the parton shower model. In this project we present the results of the impact the shower has on the reconstruction of the W-boson and top quark masses using Pythia, the Lund Monte Carlo event generator. READ MORE

4. 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

5. A new dipole-based jet clustering algorithm
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : Jet production occurs very often in particle physics experiments, and a very good understanding of how partons evolve into jets has been achieved over the last 30 years. The main tool in jet analysis is jet clustering algorithms, and because the problem of clustering particles back to initial partons can not be solved exactly, many different algorithms have been developed.
