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…
Sign of the coupling and implication for new physics
Dipankar Das, Anirban Kundu, Miguel Levy +3
The magnitudes of the couplings of the scalar resonance at 125 GeV with the SM particles are found to be consistent with those of the SM Higgs boson. However, the signs are not exp…
A Modular Littlest Seesaw
Ivo de Medeiros Varzielas, Steve F. King, Miguel Levy
We extend the littlest modular seesaw to a Grand Unified scenario based on endowed with three modular symmetries. We leverage symmetry protected zeroes in the leptoni…
