1. 1. Studies of the axial-vector transition form factors of the process Ω− → W−Ξ0 in chiral perturbation theory

   University essay from Uppsala universitet/Kärnfysik

   Author : Hélène De Munck; [2023]
   Keywords : Transition form Factors; Next-to-next-to-leading order; chiral perturbation theory; axial-vector; Ω− → W−Ξ0;

   Abstract : This work is included in a broader research of the hadron theory group of Uppsala University and its collaborators tackling the quest for an understanding of the quark distribution inside hadrons by joining threedifferent approaches of QCD namely chiral perturbation theory, dispersion theory and lattice QCD. This thesis contributes by computing in chiral perturbation theory, the quark-masses dependence of form factors. READ MORE

3. 2. On the vector transition form factors in the Ω- → Ξ0 W- decay

   University essay from Uppsala universitet/Kärnfysik

   Author : Magnus Bertilsson; [2023]
   Keywords : QCD; Form factors; Vector form factors; Chiral perturbation theory; One-loop diagrams; Hadrons; Hadron physics; Hyperon decay; Hadron structure;

   Abstract : To learn more about the structure of hadrons we study form factors. In the semi-leptonic decay Ω- → Ξ0W- two types of form factors arise namely the vector and axial-vector transition form factors. READ MORE

4. 3. Calculating scattering amplitudes in φ3 and Yang-mills theory using perturbiner methods

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Daniel Nilsson; Magnus Bertilsson; [2022]
   Keywords : QFT; Quantum; Quantum field theory; scattering amplitudes; Berends Giele Currents; feynman diagrams; n particle scattering;

   Abstract : We calculate tree-level scattering amplitudes in φ^3 theory and Yang-Mills theory by means of the perturbiner expansion. This involves solving the Euler-Lagrange equations of motion perturbatively via a multi-particle ansatz, and using Berends-Giele recursion relations to extract the solution from simple on-shell data.

5. 4. Polarizability and Orientation Dynamics of Small Proteins

   University essay from Uppsala universitet/Materialteori

   Author : Ebba Koerfer; [2022]
   Keywords : Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

   Abstract : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. READ MORE

6. 5. Reed-Solomon Codes - Error Correcting Codes

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Isabell Skoglund; [2020]
   Keywords : ;

   Abstract : In the following pages an introduction of the error correcting codes known as Reed-Solomon codes will be presented together with different approaches for decoding. This is supplemented by a Mathematica program and a description of this program that gives an understanding in how the choice of decoding algorithms affect the time it takes to find errors in stored or transmitted information.
