Intermediate Charge-Breaking Phases and Symmetry Non-Restoration in the 2-Higgs-Doublet Model
Mayumi Aoki, Lisa Biermann, Christoph Borschensky +3
The Higgs potentials of extended Higgs sectors exhibit a complex and interesting vacuum structure. When travelling back in time, i.e. going to higher temperatures, the structure ma…
Symmetries for the 4HDM: extensions of cyclic groups
Jiazhen Shao, Igor P. Ivanov
Multi-Higgs models equipped with global symmetry groups, either exact or softly broken, offer a rich framework for constructions beyond the Standard Model and lead to remarkable ph…
Limiting FCNC induced by a CP symmetry of order 4
Duanyang Zhao, Igor P. Ivanov, Roman Pasechnik +1
CP4 3HDM is a three-Higgs-doublet model based on the symmetry of order 4 (CP4). Imposing CP4 leads to remarkable connections between the scalar and Yukawa sectors and unavoida…
Threshold effects in high-energy vortex state collisions
Bei Liu, Igor P. Ivanov
Collisions of particles prepared in non--plane-wave states with a non-trivial phase structure, such as vortex states carrying an adjustable orbital angular momentum (OAM), open nov…
Promises and challenges of high-energy vortex states collisions
Igor P. Ivanov
Vortex states of photons, electrons, and other particles are non--plane-wave solutions of the corresponding wave equation with helicoidal wave fronts. These states possess an intri…
Exploring multi-Higgs models with softly broken large discrete symmetry groups
Ivo de Medeiros Varzielas, Igor P. Ivanov, Miguel Levy
We develop methods to study the scalar sector of multi-Higgs models with large discrete symmetry groups that are softly broken. While in the exact symmetry limit, the model has ver…
