1. 1. Exploring a Two Higgs Doublet Model with a U(1) Family Symmetry and a Complex Singlet

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Michal Nowak; [2021]
   Keywords : Two Higgs Doublet Model; Complex Singlet Extension; Phenomenology; Physics Beyond the Standard Model; Branco-Grimus-Lavoura Model; Physics and Astronomy;

   Abstract : In this project a two Higgs doublet model with a complex singlet and an extra family symmetry providing a mechanism for suppression of flavor changing neutral currents is explored. The goal is to investigate the phenomenological consistency of the model using a custom software framework. READ MORE

3. 2. Phenomenology of a Three Higgs Doublet Model with a U(1)xZ2 flavour symmetry

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Ian Padilla; [2019]
   Keywords : Phenomenology Physics Beyond the Standard Model Three Higgs Doublet Model Flavour Symmetry; Physics and Astronomy;

   Abstract : We have studied the main features and the phenomenological consistency of a family-nonuniversal Three Higgs Doublet Model (3HDM) with a softly broken U(1)xZ2 family symmetry that enforces the flavour hierarchies in the Standard Model (SM) while implementing a tree-level Flavour Changing Neutral Current (FCNC) suppression in a Branco-Grimus-Lavoura way. Furthermore, the alignment limit is imposed in the scalar sector to enforce the physical scalar spectrum to accommodate a SM-like Higgs boson. READ MORE
