More about modular symmetries and non-invertible properties in magnetized compactifications
Tatsuo Kobayashi, Shuhei Miyamoto, Riku Nakano +2
We study the modular symmetry in magnetized compactifications. The zero-modes with different Scherk-Schwarz phases transform each other. A generic model does not include modes with…

Residual group-like symmetries in selection rules without group actions
Jun Dong, Tatsuo Kobayashi, Shuhei Miyamoto +2
We analyze loop-induced group-like symmetries in theories where fields are labeled by basis elements of a fusion algebra constructed from the conjugacy classes of finite groups. Al…

Yukawa Textures with Enhanced Symmetries in Heterotic Calabi-Yau Compactifications
Jun Dong, Tatsuo Kobayashi, Shuhei Miyamoto +1
We clarify the structure of Yukawa couplings and mass matrices for matter fields in heterotic string theory on smooth Calabi-Yau threefolds with standard embedding. The topological…
