1. 6. Reconstruction of spin observables in the pbar p → anti-Ω Ω reaction

   University essay from Uppsala universitet/Kärnfysik

   Author : Arnela Hrbat; [2023]
   Keywords : ;

   Abstract : The aim of this project was to reconstruct the spin observables of hyperons in the bar p → anti-ΩΩ reaction using a novel formalism that was developed at Uppsala University, using the standard event generator EvtGen. EvtGen is the event generator that is used in PandaRoot, but in this work, it is used as the standalone software. READ MORE

3. 7. An Introduction to Symmetry Protected Topological Phases

   University essay from Uppsala universitet/Teoretisk fysik

   Author : David Petrovic; [2023]
   Keywords : ;

   Abstract : In this thesis, we aim to display characteristics of symmetry protected topological phases within quantum mechanics (QM). Building on well known aspects of QM, we relate the formalism to basic group representation theory, and review the connection between projective symmetries and protected vacuum degeneracies.

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

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

   Abstract : 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. READ MORE

5. 9. Asymptotic Symmetries and Dressed States in QED and QCD

   University essay from Stockholms universitet/Fysikum

   Author : Saimeng Zhou; [2023]
   Keywords : Dressed states; Large gauge transformation; Faddeev-Kulish formalism; Generalized coherent state operator; Wilson line; Infrared divergence; Asymptotic Hamiltonian; QED; QCD;

   Abstract : Infrared divergences arising in theories with massless gauge bosons have been shown to cancel in scattering amplitudes when using dressed states constructed from the Faddeev- Kulish approach to the asymptotic states. It has been established that these states are closely related to asymptotic symmetries of the theory, that is, non-vanishing gauge trans- formations at the asymptotic boundary. READ MORE

6. 10. Generating Wikipedia Articles with Grammatical Framework : A Case Study

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Keivan Matinzadeh; [2023]
   Keywords : Grammatical Framework; Computational Linguistics; Natural Language Generation; Computer Science; Grammatical Framework; Beräkningslingvistik; Textgenerering; Datavetenskap;

   Abstract : Natural language generation is a method used to produce understandable texts in human languages from data [1]. Grammatical Framework is a grammar formalism and a functional programming language using a nonstatistical approach to build natural language applications. READ MORE
