Minimal Radiative Neutrino Masses
Christiane Klein, Manfred Lindner, Sebastian Ohmer
We conduct a systematic search for neutrino mass models which only radiatively produce the dimension-5 Weinberg operator. We thereby do not allow for additional symmetries beyond t…
Emerging Internal Symmetries from Effective Spacetimes
Manfred Lindner, Sebastian Ohmer
Can global internal and spacetime symmetries be connected without supersymmetry? To answer this question, we investigate Minkowski spacetimes with d space-like extra dimensions and…
Unification and Local Baryon Number
Pavel Fileviez Perez, Sebastian Ohmer
We investigate the possibility to find an ultraviolet completion of the simple extensions of the Standard Model where baryon number is a local symmetry. In the context of such theo…
Gravitational Waves as a New Probe of Bose-Einstein Condensate Dark Matter
P. S. Bhupal Dev, Manfred Lindner, Sebastian Ohmer
There exists a class of ultralight Dark Matter (DM) models which could form a Bose-Einstein condensate (BEC) in the early universe and behave as a single coherent wave instead of i…
Simple Left-Right Theory: Lepton Number Violation at the LHC
Pavel Fileviez Perez, Clara Murgui, Sebastian Ohmer
We propose a simple left-right symmetric theory where the neutrino masses are generated at the quantum level. In this context the neutrinos are Majorana fermions and the model has…
