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. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Emil Beiersdorf; [2023]
   Nyckelord :Quantum chirality; chirality; spin interaction; Heisenberg interaction; DM interaction; quantum physics; quantum mechanics; molecular nanomagnet; mathematical physics; theoretical physics; Kvantkiralitet; kiralitet; spinninteraktioner; Heisenberginteraktion; DMinteraktion; kvantfysik; kvantmekanik; molekylär nanomagnet; matematisk fysik; teoretisk fysik;

   Sammanfattning : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. LÄS MER

4. 3. 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

5. 4. Biocatalysis in Pickering emulsions

   Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Författare :Christine Vera Isabel Schmidt; [2023]
   Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

   Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

7. 5. A numerical implementation of the chirality-flow formalism

   Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Författare :Zenny Wettersten; [2022]
   Nyckelord :chirality-flow; chirality; flow; spinor-helicity; tree-level; diagram; amplitude; generator; numerical; Physics and Astronomy;

   Sammanfattning : The chirality-flow formalism has proven to make amplitude calculations in the Standard Model analytically simple in comparison to previously established formalisms. To test the viability of the chirality-flow formalism for numerical implementations, a Chiral Automized Flow Extension (CAFE) for MadGraph5_aMC@NLO has been developed to compare amplitude evaluation time scaling between the two.
