1. 1. Implementing the chirality-flow formalism for tree-level massless QCD in MadGraph

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Adam Warnerbring; [2023]
   Nyckelord :Theoretical physics; The chirality-flow formalism; Physics and Astronomy;

   Sammanfattning : The chirality-flow formalism provides a simple but efficient way to rewrite and evaluate Feynman diagrams and has recently been shown to also optimize automated numerical scattering matrix element evaluations in massless tree-level QED. In this thesis we extend the numerical QED model to massless tree-level QCD in the MadGraph5_aMC@NLO framework. LÄS MER

3. 2. MadGraph Implementations of the Chirality-Flow Formalism for QED

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Emil Boman; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. LÄS MER

4. 3. Long-Lived Particles from exotic Higgs decays at the FCC-ee

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Magdalena Vande Voorde; [2023]
   Nyckelord :;

   Sammanfattning : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

5. 4. Upgrade of the LHCb simulation framework with advanced particle event generators

   Master-uppsats, KTH/Fysik

   Författare :Ruben Pozzi; [2023]
   Nyckelord :;

   Sammanfattning : The LHCb experiment is one of the main detectors in function at the Large Hadron Collider (LHC) at CERN. In order to interpret the data recorded by the detector, Monte Carlo (MC) samples are used as a way to validate and test theories by comparison with the experimental data. LÄS MER

7. 5. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model

   Master-uppsats, Uppsala universitet/Högenergifysik

   Författare :Anton Olsson; [2022]
   Nyckelord :Dark matter; particle phenomenology; LHC; MadGraph; standard model; beyond standard model;

   Sammanfattning : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. LÄS MER
