Kinematic surprises in twisted particle collisions
Igor P. Ivanov, Nikolai Korchagin, Alexandr Pimikov +1
"Twisted particles" refer to non-plane-wave states of photons, electrons, hadrons, or any other particle which carry non-zero, adjustable orbital angular momentum with respect to t…
Boundedness from below in the three-Higgs-Doublet model
Francisco S. Faro, Igor P. Ivanov
Establishing if multi-Higgs potentials are bounded from below (BFB) can be rather challenging, and it may impede efficient investigation of all phenomenological consequences of suc…
Recognizing symmetries in 3HDM in basis-independent way
Ivo de Medeiros Varzielas, Igor P. Ivanov
Higgs doublets may come in three generations. The scalar sector of the resulting three-Higgs-doublet model (3HDM) may be constrained by global symmetry groups leading to charac…
Beyond basis invariants
Igor P. Ivanov, Celso C. Nishi, Andreas Trautner
Physical observables cannot depend on the basis one chooses to describe fields. Therefore, all physically relevant properties of a model are, in principle, expressible in terms of…
