1. 1. A numerical implementation of the chirality-flow formalism

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Keywords : chirality-flow; chirality; flow; spinor-helicity; tree-level; diagram; amplitude; generator; numerical; Physics and Astronomy;

   Abstract : 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.

3. 2. The two-Higgs-doublet modelas an explanation for the muon (g−2) discrepancy

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Zenny Wettersten; [2020]
   Keywords : Beyond Standard Model; BSM; CP violation; Higgs Physics; two Higgs doublet model; 2hdm; Physics and Astronomy;

   Abstract : The general Z2-violating two-Higgs-doublet model (2HDM) is analysed as an explanation for the discrepancy between Standard Model predictions and experimental measurements of the muon anomalous magnetic dipole moment ∆aµ, with the condition that it does not provide an electron electric dipole moment |eEDM| larger than experimental bounds. Several point studies of individual 2HDM parameter space points are made to show large-scale cancellation among Barr-Zee 2-loop contributions to |eEDM| at large Yukawa lepton sector magnitudes, as well as an approximately linear growth of total aµ contribution when those magnitudes are rescaled by a common factor, reaching the same order as ∆aµ.
