Non-Invertible Froggatt-Nielsen Symmetry
Hajime Otsuka, Ryo Yokokura
We investigate non-invertible completions of anomalous flavor symmetries and their application to Dirac neutrino masses. We formulate symmetry defects dressed by topological quantu…

Stringy constraints on primordial electromagnetic fields in axion inflation
Hajime Otsuka, Ryo Yokokura
We study primordial electromagnetic fields in effective actions of string theory. In contrast to a conventional scenario of producing primordial electromagnetic fields induced by t…

Sequestered String Models imply Split Supersymmetry
Michele Cicoli, Alessandro Cotellucci, Hajime Otsuka
Sequestering is a promising mechanism in 4D string models to reconcile high-scale inflation with low-energy supersymmetry. In this scenario the MSSM lives on branes at singularitie…
