Gravity tidings from domain walls: Flavour hierarchies are making waves
Stefan Antusch, Ivo de Medeiros Varzielas, Miguel Levy
Explaining the observed charged fermion mass hierarchies points to flavour symmetries inducing a suppression of the lighter species' masses. When the symmetries are global, it is e…
Soft Symmetry Breaking as a Nonstandard Source of Mass: Phenomenological Insights from the Two-Higgs-Doublet Model
Dipankar Das, Miguel Levy, Shreya Pandey +2
The soft-breaking parameter, , frequently appearing in the 2HDM scalar potential is much more remarkable than being just a nonstandard parameter that helps make the BSM s…
Gravity-assisted neutrino masses
Stefan Antusch, Salvador Centelles Chuliá, Miguel Levy
Gravity is generally expected to violate global symmetries, including lepton number. However, neutrino masses from the Planck-suppressed Weinberg operator are typically too small t…
Optical Vortex Spin-Orbit Control of Refractive Index in Iron Garnets
Seth Nelson, Cong Yu, Daniel Watson +2
The interaction between light's angular momentum (AM) and material systems has unlocked new avenues in structured photonics, including in magneto-optical (MO) materials. While spin…
Flavor puzzle in three Higgs-doublet models: Insights from BGL and lessons from flavor data
Dipankar Das, Miguel Levy, Anugrah M. Prasad
We study a variant of the 3HDM, referred to as the BGL-3HDM, incorporating a symmetry, which can distinguish the primary sources of mass for different fermion…
