  1. 6. Multiplicity and Classification of Final State Particles in Herwig7

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Carl Rosenkvist; [2021]
    Keywords : MPI; multiple parton interactions; multi-parton interactions; event generation; cluster; cluster classification; Herwig7; Physics and Astronomy;

    Abstract : In this work we investigate the hard and soft interactions in the multiple parton interactions (MPI) simulation in Herwig7. The investigation covers how the number of soft and hard interactions in an event is linked to the multiplicity of final state particles. READ MORE

  3. 7. Signal background interference effects in lepton trident events with a new low mass mediator

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Patricia Andrea Gutiérrez García; [2020]
    Keywords : dark matter; pythia; matrix element corrections; LDM; Dire; Madgraph; dark photons; Physics and Astronomy;

    Abstract : 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

  4. 8. Investigation of Impact Parameter Profiles in Multi-Parton Interactions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Martin Korsfeldt; [2020]
    Keywords : Angantyr; Impact Parameter; Multiparton Interaction; Physics and Astronomy;

    Abstract : 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. READ MORE

  6. 10. 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
