1. 11. Three-body decay as a baryon polarizer

   University essay from Uppsala universitet/Kärnfysik

   Author : Carl Johan Königsson; [2023]
   Keywords : Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

   Abstract : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. READ MORE

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

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

   Author : Emil Boman; [2023]
   Keywords : Physics and Astronomy;

   Abstract : 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. READ MORE

4. 13. The Bloch-Messiah theorem and its application to overlaps

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Frieder Selisko; [2023]
   Keywords : Physics and Astronomy;

   Abstract : The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. READ MORE

5. 14. Pure Yang-Mills amplitudes in 5 Dimensions : A study of vector boson amplitudes at 4 and 5 points

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Athanasios Voutouras; [2023]
   Keywords : Yang-Mills; Scattering; Amplitudes; QFT;

   Abstract : In this text we explore the case of pure Yang-Mills amplitudes in 5 spacetime dimensions for vector particles. Extending current toolsets such as the Spinor-Helicity formalism in 5D would be beneficial to the study of the various cases of super Yang-Mills and supergravity. READ MORE

6. 15. Methodology for analysis of vibration isolating systems

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Jonas Olsson; [2023]
   Keywords : Vibration;

   Abstract : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. READ MORE
